Sample approval is one of the most important stages in men’s denim manufacturing.

A sample allows the buyer to verify whether the manufacturer has correctly interpreted:

• Fit
• Measurements
• Fabric
• Construction
• Wash
• Trims
• Branding
• Packaging

Approving a sample too quickly can create expensive problems during bulk production.

A small error in one sample can be repeated across hundreds or thousands of finished garments.

The buyer should therefore treat sample approval as a technical and commercial decision, not a casual visual check.

Why Sample Approval Matters

The approved sample becomes a key production reference.

It may be used by:

• Pattern team
• Cutting team
• Sewing team
• Wash unit
• Finishing team
• Quality-control team
• Packing team
• Third-party inspector

A complete approval process helps reduce:

• Fit complaints
• Measurement variation
• Incorrect wash shades
• Construction defects
• Hardware problems
• Label mistakes
• Packaging errors
• Production disputes

The sample should reflect the final product as closely as possible before bulk manufacturing begins.

Types of Men’s Denim Jeans Samples

Not every sample has the same purpose.

A brand may receive several sample types during development.

Sample type	Main purpose	Buyer should review
Development sample	Tests the initial design idea	General shape, construction and feasibility
Fit sample	Tests measurements and silhouette	Fit, balance, comfort and movement
Wash sample	Tests shade and finishing	Color, fading, whiskers, softness and shrinkage
Size-set sample	Checks grading across sizes	Proportion, size progression and fit consistency
Pre-production sample	Confirms final approved specification	All product details before bulk production
Shipment sample	Represents finished bulk goods	Final appearance, packaging and overall quality

A development sample should not automatically be treated as a final production sample.

Each sample must be evaluated according to its intended purpose.

Development Sample

The first development sample helps determine whether the product concept is technically workable.

Check:

• Overall silhouette
• Basic construction
• Pocket shape
• Design balance
• Fabric suitability
• Approximate wash direction
• Branding concept

At this stage, several corrections may still be necessary.

Fit Sample

A fit sample focuses on:

• Waist
• Rise
• Seat
• Thigh
• Knee
• Leg opening
• Inseam
• Garment balance
• Comfort
• Mobility

The fit sample should normally use a fabric with similar weight, stretch and recovery to the final approved fabric.

A very different fabric can produce misleading fit results.

Wash Sample

A wash sample evaluates:

• Final shade
• Fading
• Whiskers
• Contrast
• Softness
• Abrasion
• Distressing
• Shrinkage
• Hardware reaction

The wash should be reviewed on the intended production fabric whenever possible.

Size-Set Sample

A size-set includes several or all sizes from the range.

It helps confirm whether grading remains balanced.

Check:

• Waist increments
• Rise progression
• Seat and thigh growth
• Knee and hem proportions
• Pocket placement
• Yoke proportion
• Overall silhouette

A good base-size sample does not guarantee that every graded size will fit correctly.

Pre-Production Sample

The pre-production sample should represent the final product.

It should use approved:

• Fabric
• Wash
• Pattern
• Measurements
• Trims
• Labels
• Stitching
• Branding
• Packaging

Bulk production should not begin while major pre-production issues remain unresolved.

Sample Approval Process

A reliable approval process follows clear steps.

1. Confirm the sample version.
2. Review the latest tech pack.
3. Check the correct fabric and wash.
4. Measure the garment.
5. Evaluate fit on the intended body profile.
6. Test movement and comfort.
7. Inspect construction.
8. Review stitching and reinforcement.
9. Check trims and hardware.
10. Review branding and labels.
11. Check grading when applicable.
12. Review packaging.
13. Record all comments.
14. Decide whether to approve, conditionally approve or reject.
15. Issue written confirmation.

Step 1: Confirm the Sample Identity

Before inspecting the garment, confirm:

• Brand
• Style name
• Style number
• Sample type
• Sample size
• Tech pack version
• Fabric code
• Wash code
• Date
• Revision number

A sample may appear correct but belong to an older revision.

Do not inspect it without confirming which specification was used.

Step 2: Use the Latest Tech Pack

Keep the latest tech pack beside the sample during inspection.

The document should contain:

• Measurement chart
• Technical sketches
• Construction notes
• Fabric details
• Wash reference
• Trim list
• Label placement
• Packaging instructions

A complete men’s denim jeans tech pack helps create a measurable approval process.

Do not approve based only on memory or informal messages.

Step 3: Check the Sample Under Good Lighting

Wash shade and fabric appearance can look different under poor or artificial lighting.

Review the sample in:

• Neutral daylight
• Consistent indoor lighting
• A clean inspection area

Avoid evaluating shade next to strongly colored walls or surfaces.

When comparing two samples, place them under the same lighting conditions.

Step 4: Allow the Garment to Rest

A sample may become compressed during shipping.

Before measuring:

• Remove it from packaging.
• Lay it flat.
• Allow the fabric to relax.
• Smooth the garment without stretching it.
• Follow the agreed conditioning method.

Stretch fabrics may require additional relaxation time.

Use the same preparation method for every measurement review.

How to Measure the Sample Correctly

Measurements must follow the method defined in the tech pack.

Do not change the measuring technique between samples.

Common tools include:

• Flexible measuring tape
• Flat inspection table
• Ruler
• Angle guide
• Measurement diagram
• Approved sample

Important Measurement Points

Common men’s denim measurements include:

• Waist
• Front rise
• Back rise
• Seat
• Thigh
• Knee
• Leg opening
• Inseam
• Outseam
• Waistband height
• Fly length
• Front pocket opening
• Back pocket dimensions
• Yoke depth

Sample Measurement Review Table

Measurement point	Specification	Actual sample	Tolerance	Result
Waist	84 cm	85 cm	±1 cm	Pass
Front rise	27 cm	27.8 cm	±0.5 cm	Fail
Back rise	38 cm	38.2 cm	±0.5 cm	Pass
Thigh	61 cm	60 cm	±1 cm	Pass
Inseam	81 cm	79.5 cm	±1 cm	Fail
Leg opening	38 cm	38.5 cm	±1 cm	Pass

This table makes approval comments easier to understand.

Finished vs Before-Wash Measurements

Confirm whether the sample is being measured:

• Before washing
• After washing
• After pressing
• After garment conditioning

For finished jeans, the approval measurements should normally reflect the final post-wash product.

The manufacturer may also maintain separate before-wash specifications for production control.

How to Check Waist Measurement

The waist should be measured according to the agreed method.

Common variables include:

• Waistband aligned or naturally curved
• Button fastened or open
• Garment relaxed or stretched
• Half-waist or full circumference

The method must remain consistent.

Also check:

• Waistband shape
• Gaping
• Excessive stretch
• Waistband rolling
• Button placement

How to Check Rise

Front and back rise influence comfort and appearance.

A rise that is too short may create:

• Tightness
• Pulling
• Restricted movement
• Poor seat fit

A rise that is too long may create:

• Excess fabric
• Dropping
• Wrinkling
• Poor silhouette

Review rise both through measurement and on-body fit.

How to Check Seat and Thigh

The seat and thigh should provide the intended level of ease.

Look for:

• Horizontal stress lines
• Excessive pulling
• Loose fabric
• Twisting
• Pocket distortion
• Restricted movement

Ask the fit model to:

• Stand
• Walk
• Sit
• Bend
• Climb a step
• Move naturally

A sample that looks acceptable while standing may feel uncomfortable during movement.

How to Check Knee and Leg Shape

Confirm:

• Knee position
• Taper
• Straightness
• Symmetry
• Leg opening
• Side-seam alignment

The knee point should match the intended pattern and wearer proportions.

Uneven leg shape can indicate:

• Pattern imbalance
• Cutting error
• Sewing distortion
• Wash shrinkage
• Fabric skew

How to Check Inseam and Outseam

Measure both legs when necessary.

Check:

• Length consistency
• Seam twisting
• Hem balance
• Side-seam alignment
• Inseam smoothness

Leg twisting should be investigated because it may come from fabric skew or production handling.

Fit Testing on the Correct Person

Fit should be tested on someone close to the target customer profile.

The fit model should match the intended:

• Waist
• Height
• Seat
• Thigh
• Body proportions

Avoid using only the brand owner unless that person represents the target customer.

Fit Review Questions

Ask:

• Does the waistband feel secure?
• Is there enough room in the seat?
• Is the thigh comfortable?
• Does the rise feel correct?
• Can the wearer sit comfortably?
• Does the fabric recover after movement?
• Is the leg shape balanced?
• Is the hem opening appropriate?
• Are pockets comfortable and functional?

Record practical answers instead of relying only on visual judgment.

Fit Approval Table

Area	Too tight	Correct	Too loose	Comment
Waist		✓		Secure without pressure
Seat	✓			Add ease
Thigh		✓		Movement acceptable
Knee		✓		Shape correct
Leg opening			✓	Reduce opening
Rise		✓		Comfortable

Check Garment Balance

Garment balance affects how the jeans hang on the body.

Signs of imbalance include:

• Waistband rising at front or back
• Side seams moving forward
• Twisting legs
• Excess fabric below the seat
• Uneven hem
• Pulling around the crotch

Balance issues may require pattern corrections rather than simple measurement changes.

Fabric Evaluation

Fabric should be reviewed for:

• Weight
• Composition
• Stretch
• Recovery
• Hand feel
• Surface texture
• Shade
• Shrinkage
• Durability
• Wash response

Brands can compare available denim fabric selections before final approval.

Stretch and Recovery Test

For stretch denim:

1. Measure a selected area.
2. Stretch it through normal wear movement.
3. Allow it to recover.
4. Check whether it returns close to its original shape.

Poor recovery can lead to:

• Bagging at knees
• Loose waistband
• Seat deformation
• Reduced product life

Shrinkage Review

Compare:

• Before-wash measurements
• After-wash measurements
• Required finished measurements

Check whether shrinkage is:

• Within expected limits
• Consistent across garment areas
• Properly compensated in the pattern

Excessive shrinkage can affect:

• Waist
• Inseam
• Rise
• Thigh
• Leg opening

Fabric Shade Review

Check for:

• Uneven dyeing
• Barre effects
• Shade differences between panels
• Unintended streaks
• Poor lot consistency
• Excessive color transfer

Natural denim character may be acceptable, but production limits should be agreed.

Wash Approval

The wash must be compared with the approved reference.

Review:

• Overall shade
• Contrast
• Whiskers
• Thigh fading
• Knee fading
• Seat fading
• Back-knee effects
• Pocket abrasion
• Seam appearance
• Hand feel
• Distressing
• Cleanliness

Wash Approval Table

Wash feature	Approved standard	Sample result	Decision
Overall shade	Dark indigo	Slightly lighter	Revise
Whiskers	Low contrast	Correct	Approve
Thigh fading	Minimal	Excessive	Revise
Hand feel	Soft	Correct	Approve
Hem abrasion	None	Present	Reject
Shade consistency	Controlled	Acceptable	Approve

Physical Wash Reference

A physical sample or wash panel is usually more reliable than a screen image.

Photographs can be affected by:

• Lighting
• Camera settings
• Screen calibration
• Editing
• Compression

Keep one approved physical reference for comparison with bulk production.

Check Wash Placement

Effects should be:

• Symmetrical where required
• Correctly positioned
• Suitable for the fit
• Consistent with the brand identity
• Within approved intensity

Poorly positioned whiskers or fading can make the product look unnatural.

Check Wash Damage

Inspect for:

• Weak seams
• Fabric holes
• Broken threads
• Damaged labels
• Corroded hardware
• Excessive abrasion
• Uneven distressing
• Unwanted staining

Wash processes should create the intended appearance without weakening the product beyond acceptable limits.

Construction Inspection

Review how the garment is assembled.

Important areas include:

• Waistband
• Fly
• Front pockets
• Coin pocket
• Back pockets
• Yoke
• Inseam

Reinforcement should match the approved construction specification.

Pocket Inspection

Check:

• Front pocket opening
• Pocket depth
• Coin pocket
• Back pocket shape
• Pocket alignment
• Decorative stitching
• Reinforcement
• Pocket bag material

Back pockets should be balanced in:

• Height
• Width
• Angle
• Distance from center back
• Distance from yoke

Small differences can change the overall appearance.

Fly Inspection

Check:

• Zipper length
• Zipper operation
• Button placement
• Fly shape
• Topstitching
• Internal construction
• Bartacks
• Fabric coverage

The zipper should move smoothly without catching fabric.

Waistband Inspection

Review:

• Finished height
• Shape
• Interlining
• Buttonhole
• Button position
• Topstitching
• Belt-loop placement
• Internal finish
• Label placement

The waistband should lie cleanly without twisting or rolling.

Belt-Loop Inspection

Check:

• Number
• Width
• Length
• Placement
• Reinforcement
• Alignment

All loops should be securely attached.

Hem Inspection

Review:

• Hem depth
• Stitch type
• Thread color
• Symmetry
• Leg length

• Pocket bag
• Sewing thread

Button and Rivet Checks

Confirm:

• Correct finish
• Correct size
• Correct logo, when applicable
• Secure attachment
• Smooth edges
• Correct placement
• No corrosion
• No fabric damage

Hardware should not have sharp edges that could affect safety or product quality.

Zipper Checks

Test the zipper several times.

Check:

• Smooth movement
• Locking function
• Correct length
• Correct tape color
• Strong attachment
• No fabric catching

Label Inspection

Review:

• Brand spelling
• Logo
• Size
• Fiber content
• Care instructions
• Country of origin
• Style code
• Label position
• Label orientation
• Attachment quality

A small label error can affect an entire production order.

Branding Inspection

Branding may include:

• Waist patch
• Pocket embroidery
• Printing
• Woven labels
• Branded hardware
• Hang tags

Confirm:

• Size
• Position
• Color
• Artwork
• Method
• Alignment
• Durability

Brands can review Wanza Jeans’ embroidery options and printing methods before final approval.

Embroidery Review

Check:

• Artwork accuracy
• Thread color

• Backing
• Loose threads

Heavy embroidery may distort pocket fabric if not properly developed.

Printing Review

Check:

• Artwork size
• Color
• Clarity
• Placement
• Adhesion
• Cracking
• Wash durability

The approved sample should represent the expected production method.

Do not only verify whether measurements increase.

Confirm whether the overall fit remains balanced.

Key Grading Areas

• Waist
• Seat
• Front rise
• Back rise
• Thigh
• Knee
• Leg opening
• Pocket dimensions
• Pocket placement
• Yoke depth
• Belt-loop position

Grading Comparison Example

Measurement	Size 30	Size 32	Size 34	Size 36
Waist	79 cm	84 cm	89 cm	94 cm
Seat	99 cm	104 cm	109 cm	114 cm
Thigh	59 cm	61 cm	63 cm	65 cm
Front rise	25.5 cm	26.5 cm	27.5 cm	28.5 cm
Leg opening	37 cm	38 cm	39 cm	40 cm

These figures are examples only.

Grade rules should match the intended fit and customer profile.

Common Size-Set Problems

• Smaller sizes become too narrow at thigh.
• Larger sizes have excessive leg width.
• Rise does not increase correctly.
• Pockets look too small on larger sizes.
• Yoke depth becomes unbalanced.
• Belt loops move away from intended positions.

Size-set approval should focus on proportion, not only numbers.

Packaging Sample Review

Packaging should be approved before bulk packing begins.

Check:

• Folding method
• Polybag
• Size sticker
• Barcode
• Product insert
• Hang tag
• Carton quantity
• Assortment
• Shipping marks

Brands can review custom packaging options when planning private label orders.

Packaging Checklist

• Garment is folded correctly.
• Labels remain visible where required.
• Polybag size is suitable.
• Barcode scans correctly.
• Size sticker matches the garment.
• Product insert is accurate.
• Carton assortment is correct.
• Shipping marks match instructions.
• Packaging protects the product.

Compare Sample With Target Price

A technically good sample may still be commercially unsuitable.

Review whether the final product supports:

• Target retail price
• Intended margin
• Brand position
• Customer expectation
• Sales channel

For example, a product may become too expensive because of:

• Custom hardware
• Complex wash
• Multiple labels
• Heavy embroidery
• Premium packaging

Sample approval should include both quality and commercial viability.

Approval Status Options

A sample does not have to receive only a simple yes or no.

Use clear status categories.

Approved

The sample is accepted for the next production stage.

Approved With Minor Comments

The sample is accepted only if small corrections are applied and verified.

Use this carefully.

Minor comments may include:

• Thread trimming
• Small label-position adjustment
• Packing correction

Revise and Resubmit

A new sample is required.

Use this when issues affect:

• Fit
• Measurements
• Fabric
• Wash
• Construction
• Grading
• Branding

Rejected

The sample does not meet the product requirement and requires major redevelopment.

When to Request Another Sample

Request another sample when:

• Fit is incorrect.
• Measurements are outside tolerance.
• Fabric is different.
• Wash is not approved.
• Construction needs major changes.
• Pocket placement is wrong.
• Hardware changes.
• Branding changes significantly.
• Size grading is unverified.
• The sample uses temporary materials.

Do not approve a sample only to save development time.

Bulk correction is usually more expensive than one additional sample round.

How to Write Sample Comments

Comments should be:

• Specific
• Measurable
• Numbered
• Referenced to images
• Linked to the correct sample version

Weak vs Strong Sample Comments

Weak comment	Strong comment
Make thigh looser	Increase half-thigh measurement by 1 cm at 2.5 cm below crotch
Make wash darker	Match approved wash reference WD-03; reduce front-thigh fading
Pocket looks wrong	Move back pocket 1 cm toward center back and raise by 0.5 cm
Stitching should be better	Maintain 8–9 stitches per inch on back-pocket topstitching
Logo is too large	Reduce embroidery width from 7 cm to 5.5 cm

Clear comments make revisions easier to execute and verify.

Use Annotated Photographs

Take clear photographs of:

• Front
• Back
• Side
• Inside
• Detail areas
• Fit issues

Add:

• Arrows
• Measurement references
• Correction notes
• Comment numbers

Every photograph should identify the sample version.

Sample Comment Sheet

A comment sheet may include:

Comment number	Area	Current issue	Required correction	Priority
1	Front rise	0.8 cm above tolerance	Reduce by 0.8 cm	Major
2	Back pocket	Too low	Raise by 1 cm	Major
3	Wash	Thigh fading too strong	Reduce intensity	Major
4	Label	Slightly off-center	Reposition by 0.5 cm	Minor
5	Loose thread	Visible at hem	Trim cleanly	Minor

Maintain Revision Control

Each sample round should have:

• Sample number
• Date
• Version
• Comment sheet
• Updated tech pack
• Approval status

Example:

• Sample 1: Development
• Sample 2: Fit revision
• Sample 3: Wash revision
• Sample 4: Pre-production

Do not rely on old email chains as the only approval record.

Written Approval

Bulk production approval should be issued in writing.

Include:

• Style number
• Approved sample version
• Approved fabric
• Approved wash
• Approved measurements
• Approved trims
• Approved labels
• Approved packaging
• Date
• Authorized approver

Verbal approval can create confusion.

Approved Reference Sample

The brand and manufacturer should retain an approved sample when possible.

It can be used for:

• Bulk production comparison
• Inline inspection
• Final inspection
• Repeat orders
• Dispute resolution

The sample should be labeled clearly and protected from damage.

Pros and Cons of Detailed Sample Approval

Pros

Reduces Bulk Risk

Problems can be corrected before large-scale production.

Improves Fit Consistency

Measurements and movement are reviewed carefully.

Supports Quality Control

Production teams receive a physical and written standard.

Protects Brand Reputation

Customers receive products closer to the intended specification.

Improves Reorders

Approved references can be used for future production.

Cons

Requires More Time

Careful inspection and revisions can extend development.

May Require Additional Samples

Major changes should be physically verified.

Needs Technical Attention

The buyer must understand measurements, construction and fit.

Can Increase Development Cost

Extra rounds may add cost, but they can prevent larger bulk losses.

Common Sample-Approval Mistakes

Approving Only From Photographs

Photographs cannot fully show:

• Fit
• Fabric feel
• Stretch recovery
• Weight
• Comfort
• Construction quality

Checking Only Appearance

A sample may look attractive but have incorrect measurements or weak construction.

Ignoring Movement

Fit should be tested while sitting, walking and bending.

Approving the Wrong Fabric

Temporary sample fabric may behave differently from bulk fabric.

Ignoring Shrinkage

Final measurements must account for washing.

Checking Only One Side

Compare:

• Left and right pockets
• Both legs
• Belt loops
• Seam alignment
• Wash symmetry

Approving Without Written Comments

Verbal corrections can be forgotten or misunderstood.

Ignoring Packaging

Packaging errors can delay shipment and create retailer problems.

Skipping the Size Set

One correct base size does not confirm the full size range.

Accepting Too Many Conditional Changes

If several changes are still required, request another sample instead of approving conditionally.

Best Practices

• Use the latest tech pack.
• Confirm sample version before inspection.
• Measure on a flat surface.
• Use the same measurement method every time.
• Test fit on the target body profile.
• Evaluate movement and comfort.
• Compare wash with a physical reference.
• Check both garment sides.
• Review stitching and stress points.
• Test all hardware.
• Verify every label.
• Review size grading.
• Approve packaging before bulk packing.
• Write numbered correction comments.
• Update the master tech pack.
• Retain an approved reference sample.
• Approve bulk production in writing.

Real-World Example 1: Fit Approved Only While Standing

A brand checks a slim-fit sample on a model while standing.

The sample looks correct.

After production, customers report discomfort while sitting because:

• Front rise is too short.
• Thigh is too tight.
• Fabric stretch is limited.

The lesson:

Fit must be tested through normal movement.

Real-World Example 2: Wash Approved From a Phone Image

A buyer approves a wash using a phone photograph.

When the physical products arrive, the wash is lighter and has stronger thigh fading than expected.

The lesson:

Important wash approvals should be based on a physical sample whenever possible.

Real-World Example 3: One Size Approved

A brand approves size 32 and skips the size set.

Bulk production shows:

• Smaller sizes are too tight in the thigh.
• Larger sizes have oversized pockets.
• Rise progression is inconsistent.

The lesson:

Base-size approval does not replace grading review.

Real-World Example 4: Packaging Left Until the End

The jeans are completed before the barcode and carton assortment are confirmed.

Packing is delayed while new stickers and cartons are prepared.

The lesson:

Packaging must be approved before production reaches the final packing stage.

Real-World Example 5: Clear Written Approval

A buyer reviews the pre-production sample and issues:

• Measurement report
• Fit comments
• Wash approval
• Trim approval
• Label approval
• Packaging approval
• Signed version reference

The manufacturer has one clear production standard.

This reduces confusion during bulk manufacturing.

Industry Tips

• Use a neutral fit model who matches the target customer.
• Review the sample after it has relaxed from shipping.
• Measure every critical point, not only waist and inseam.
• Test stretch recovery at the knee and waistband.
• Compare pocket placement from both sides.
• Inspect the inside construction.
• Photograph all corrections.
• Keep comments measurable.
• Confirm whether sample trims are temporary or final.
• Check care-label information before production.
• Approve size grading before cutting bulk fabric.
• Keep a sealed approved reference sample.
• Do not approve bulk production while major comments remain open.

Final Thoughts

Sample approval is not a visual formality.

It is a structured quality-control stage that protects:

• Product fit
• Production accuracy
• Customer satisfaction
• Delivery commitments
• Brand reputation
• Manufacturing investment

A strong sample-approval process combines:

• Tech pack review
• Measurement control
• Physical fit testing
• Fabric evaluation
• Wash comparison
• Construction inspection
• Trim verification
• Grading review
• Packaging approval
• Written documentation

Do not approve a sample because it is “close enough.”

Approve it because the critical details are measurable, verified and ready for bulk production.

Frequently Asked Questions

What should I check before approving a men’s denim jeans sample?

Check measurements, fit, movement, fabric, stretch recovery, shrinkage, wash, stitching, pockets, hardware, labels, branding, size grading and packaging against the latest approved tech pack.

Can I approve a denim sample from photographs?

Photographs may help with minor visual reviews, but they cannot fully confirm fit, fabric feel, stretch, weight, comfort or construction. Physical review is recommended for important approvals.

Which size should be used for a fit sample?

Use the agreed base size and a fit model who represents the target customer. The base size should be clearly identified in the tech pack.

Do I need to approve a size-set sample?

A size set is strongly recommended because it helps verify grading and proportions across the full range. One approved base size does not guarantee that all sizes will fit correctly.

How do I approve the wash of men’s denim jeans?

Compare the sample with an approved physical wash reference. Check shade, fading, whiskers, abrasion, softness, shrinkage and acceptable variation under consistent lighting.

Should bulk production begin after the first sample?

Not unless the first sample meets the final requirements. Major issues in fit, fabric, wash, construction or grading should be corrected and verified through another sample.

What is a pre-production sample?

A pre-production sample is the final sample made with approved fabric, wash, measurements, trims, labels, branding and construction. It represents the standard expected in bulk production.

How should sample approval be documented?

Use a dated comment sheet, annotated photographs, updated tech pack and written approval identifying the exact sample version, fabric, wash, trims, labels and packaging.
