Activewear Sample Approval Checklist: Fit, Quality and PP Sign-Off

Short answer: approve an activewear sample only when its identity, measurements, fit, fabric, construction, color, branding, labels, function and required test evidence match one controlled specification. Mark every issue on photos or POMs, state the expected result, and choose approve, revise and resample, or reject. Never write “approved with comments” when those comments change the physical product. The final pre-production sample and dated tech pack must agree before bulk cutting.

Linked Sourcing uses two different approval routes:

• Ready Styles from 50 pieces per style: select an existing standard product from the private Excel catalogue, then confirm its available colors, sizes, finished-garment information, quotation and order-specific branding evidence. Request the current Ready Styles Excel catalogue and stock quotation sheet.
• Full Custom Manufacturing from 200 pieces per color and style: control the development, fit, size set, materials, construction, branding, tests and final PP sample against a versioned specification. Start a Full Custom sample review.

If you want a new fit, pattern, fabric, color, construction or performance requirement, it is not simply a 50-piece Ready Style approval. It belongs in the Full Custom route and may require more than one sample round.

Sample approval is a decision, not a polite email

A courier envelope containing a garment is not proof that every question has been answered. Before reviewing it, identify what that sample is meant to prove and what is intentionally still open.

The activewear sampling cost and timeline guide explains the purpose and timing of each stage. This checklist focuses on the buyer’s review and approval record after a sample exists.

Before fitting: identify the exact sample

Do not begin with appearance. Begin with traceability. The sample tag or report should let both parties answer:

• style number and product name;
• sample stage and round, such as Fit 2 or PP 1;
• physical size and intended wearer or fit-model reference;
• colorway and shade reference;
• main fabric code, composition claim, weight/version and supplier lot if relevant;
• trim, elastic, pad, zipper or hardware versions;
• pattern, tech pack and BOM revision numbers;
• sample completion and dispatch dates;
• declared substitutions or missing components;
• which earlier comments were meant to be closed in this round.

Photograph the sample tag and the garment front, back, inside and key details before fitting. If the identity is unclear, pause the approval: a perfect comment sheet is useless when it is attached to the wrong pattern or material version.

For physical testing or measurement comparisons, conditioning can matter. ISO 139:2005, confirmed in 2025, defines standard atmospheres for conditioning and testing textiles. A brand does not need to turn every office fit session into a laboratory, but it should not compare measurements taken under unexplained, materially different conditions and call the difference a factory defect.

The 12-part activewear sample approval checklist

1. Match the sample to the controlled documents

Place the sample beside the latest tech pack, BOM, measurement chart, color/artwork approvals and prior comment sheet. Check that the revision printed on every file is the revision the sample room used.

Use the activewear tech pack checklist to close specification gaps before approving a PP sample. If the sample looks correct but the document still contains the old instruction, bulk production has two conflicting references.

2. Measure before deciding that the fit is wrong

Measure the agreed finished-garment POMs using the same placement, garment condition, tape method and units shown in the specification. Record actual values, not only pass or fail. Prioritize fit-sensitive controls such as waist, rise, inseam, underband, strap, neckline, armhole, torso length, opening and gusset position.

Separate three questions:

1. Does the physical sample match the finished-garment specification?
2. Does that specification produce the intended fit on the target wearer?
3. Is the written bulk tolerance realistic and appropriate for that POM?

The activewear size grading and fit approval checklist explains why a body chart, garment POM, grade rule and bulk tolerance are not interchangeable.

3. Review fit, balance, coverage and movement

Use a fit model whose current measurements are recorded. Review the garment standing, sitting and performing movements relevant to the product—not only posing for a front photograph.

Depending on the style, observe:

• waistband or underband position, pressure and roll;
• front/back rise, crotch shape and gusset placement;
• neckline, armhole, cup or pad coverage;
• strap security and adjustment range;
• side-seam balance, twisting and left/right symmetry;
• compression, restriction and return after movement;
• pocket access and retention;
• hem, leg opening or sleeve movement;
• opacity and coverage at an agreed wearing stretch;
• rubbing, chafing or bulky seam placement.

Record what the wearer did and what happened. “Too tight” is incomplete; “front waistband rolls 18 mm during three deep squats on Fit 2, size M, on the recorded fit model” gives the pattern team something testable.

Use the leggings waistband roll-down and fit guide to convert that observation into a controlled review of band shape, openings, material/elastic, rise, gusset, hip/thigh pull, size and movement evidence.

If the product will be sold as compressive, graduated, zonal or supportive, use the compression activewear testing guide to keep fit observations, fabric power, garment interface pressure and consumer-benefit claims as separate approvals. For a sports bra, add the sports bra support protocol rather than approving a low/medium/high label from a standing fit sample alone.

For a built-in-bra tank, add the shelf-bra tank manufacturing checklist: turn the sample inside out, identify every layer and join, measure the outer shell and inner shelf separately, inspect the underbust band, pad/cup, pocket opening, straps and hardware, then repeat the critical fit and pad-retention checks after the agreed care route.

For any “squat-proof” or “not see-through” expectation, use the activewear opacity and squat-proof testing guide to record the exact color, size, extension, background, lighting, movement and visible pass rule before approving the sample.

4. Confirm fabric and component identity

Check the sample against approved material codes and physical references, not only a composition label. Record hand feel, structure, face/back, weight evidence, width or cut direction where relevant, shade, stretch direction, power, recovery and any declared finish.

A material can have the correct fiber percentages and still create a different fit or support level. If the sample used a substitute fabric, state exactly which decisions can be made from it and which must wait for the intended fabric.

For elastic fabrics, ASTM D4964-96(2020) covers tension and elongation measurement under specified conditions and stresses that machine setup and agreed measurement points affect comparability. The standard supplies a method; the brand and supplier still need product-specific targets.

5. Inspect seams and construction inside and outside

Turn the sample inside out. Match seam type, stitch type, thread, stitch density, seam allowance, reinforcement, bonding or tape location to the construction page. Extend stress areas as agreed and look for seam grin, popping, skipped stitches, broken thread, needle damage, puckering, raw-edge exposure and uncomfortable bulk.

ASTM D6193-16(2025) identifies stitch and seam categories and describes strength, elasticity, durability, security and appearance as characteristics of properly constructed sewn seams. It does not choose one universal seam for every legging or sports bra.

When a laboratory seam-force method is required, ISO 13935-2:2026 covers maximum force to rupture for straight sewn seams using the grab method, including certain woven stretch fabrics. Its scope does not automatically validate curved activewear seams or replace an agreed movement check on the actual garment.

Use the activewear seam strength and stretch test checklist to keep maximum seam force, seam extension, fabric bursting, woven-yarn slippage and stitch security as separate approval questions. The report must identify the exact seam zone, assembly, direction, specimen and failure mode—not only one peak number.

6. Check color, shade, prints and surface appearance

Review under agreed lighting and compare with the approved lab dip, standard, print strike-off or artwork reference. Check:

• color identity and panel-to-panel shade;
• left/right symmetry and directional nap or sheen;
• print scale, repeat, placement and distortion at stretch;
• barre, streaks, stains, snags, holes and contamination;
• lining or pad show-through;
• contrast-color transfer risk at contact points.

Do not approve a dark/light color combination solely because it looks clean before use. If rubbing or laundering colorfastness is required, specify the test and pass criteria. ISO 105-X12:2016 addresses dry and wet rubbing, while ISO 105-C06:2010, confirmed in 2026, addresses colorfastness to specified domestic or commercial laundering procedures.

Use the activewear washing, rubbing and perspiration colorfastness guide to define the exact method, specimen/color/lot coverage, adjacent materials, assessment route and separate limits for color change, staining and rubbing transfer.

The activewear color approval and lab-dip checklist separates the digital direction, physical target, named lab-dip submission, PP sample and actual bulk shade lot. A Pantone code or approved lab dip alone does not approve every production roll, trim or finished set.

7. Verify logos, labels and artwork as product components

Measure logo size and placement from a named garment reference point. Check color, orientation, surface, edge, adhesion, stretch behavior and visual distortion on-body. Verify main label, size label, care/fiber label, country information, hangtag, barcode and any warning or compliance text against the approved artwork.

The custom labels, logos and packaging guide explains why garment MOQ and component MOQ are separate. If bulk logo material or final labels were not available for an earlier fit sample, the final proof must still close those items before PP approval.

8. Operate every functional detail

Do not only look at zippers, snaps, cords, pockets, removable pads or adjusters. Use them repeatedly under the agreed condition. Check:

• zipper start, travel, end stop and guard;
• snap security and fabric distortion;
• drawcord travel, exit, anchoring and symmetry;
• pocket opening, capacity, retention and bounce;
• removable-pad access, orientation and migration;
• strap adjustment range and hardware rotation;
• bonded edges, taped seams and transfer adhesion;
• reflective or other functional trim placement and declared evidence.

If a component function has a numerical requirement, put the method and limit in the specification instead of relying on “works well.”

9. Review laundering and dimensional change using one named procedure

Measure before and after the agreed treatment, then inspect shape, twisting, puckering, seam appearance, logo/print condition, color and trim function. Record the washing machine type or procedure, detergent, temperature, cycles and drying method used.

The standards play different roles:

Writing “wash test passed” without the procedure, cycles, measurements and criteria does not create reproducible evidence.

Use the activewear shrinkage and dimensional-stability wash test guide to separate fabric change from finished-garment POMs, post-care fit, spirality/skew and wash appearance, and to build a 20-field test request.

10. Match performance proof to the claim and use case

List every claim or functional expectation and the proof needed before approval. Depending on the product, this can include stretch and recovery, seam performance, opacity, pilling/abrasion, colorfastness, dimensional stability, support, chlorine or saltwater exposure, zipper/trim durability or other market-specific requirements.

For surface durability, use the activewear pilling and abrasion test checklist to define the exact material, method, specimen state, cycles or rubs, assessment stage and acceptance rule. A pilling grade and an abrasion-to-breakdown result are not interchangeable, even when both use Martindale equipment.

For moisture claims, use the activewear moisture-wicking and quick-dry test guide to keep liquid transport, drying, water-vapour resistance and air permeability as separate results, then confirm the approved fabric in the actual garment and agreed care state.

For “anti-odor,” “odor-control” or antibacterial expectations, use the activewear anti-odor testing guide to keep deodorant chemistry, bacterial odor, antibacterial activity, wash durability and garment wear evidence separate before approving the sample or public wording.

Do not invent one universal test package for all activewear. A yoga legging, high-impact bra, swim top and lightweight running shell have different failure risks. Use current licensed methods, a qualified laboratory where required, and written brand or retailer limits.

If the project is swimwear, the swimwear chlorine, saltwater and colorfastness guide separates color-change methods from broader durability, recovery and UPF questions.

11. Confirm retail presentation and packaging

For the final approval stage, review folding, inserts, hangtag attachment, individual protection, suffocation or other required warnings, SKU/barcode, size/color identification, carton assortment, shipping marks and destination requirements.

Packaging can be approved through physical samples, artwork proofs or both, depending on risk. State which evidence controls bulk. A correct garment with the wrong barcode or destination label can still be commercially unusable.

12. Create a sealed approval record

The final record should contain:

• sample ID, stage, size, color and date;
• controlling tech pack, BOM, pattern and artwork revisions;
• measurement report with actuals;
• fit-model identity or recorded body measurements;
• review photos and issue numbers;
• wash/performance reports and their sample/material coverage;
• status of every prior comment;
• final decision, approver and approval date;
• location of the retained physical sample or sealed reference;
• list of any bulk controls that remain required.

Store the approved sample cleanly and prevent it from being borrowed, altered or relabeled without a record. When physical references are held in different countries, both buyer and factory should retain matching photographs and revision identifiers.

Product-specific risks to add to the checklist

This table identifies questions, not automatic pass limits. Put the intended use and acceptance criteria into the product specification before testing.

How to write sample comments that can be closed

Use one consolidated comment sheet per round. Give each issue a stable ID and keep closed issues visible in the history.

Circle or arrow the exact area on photographs, but do not draw an unexplained line that can be interpreted as either a pattern edge or a finished measurement. If a requested change affects another POM, seam, artwork position or grade, state that dependency.

Choose one of four clear dispositions

Approve

Use only when the sample and controlled documents match and no product-changing item remains open. State the sample ID, revision and approval date.

Approve the reviewed stage, not the whole product

You may approve a concept direction or base fit while clearly listing what that stage did not evaluate. For example: “Fit 2 base size approved for measurements and balance in fabric F-07; final color, logo, labels, wash result and PP sample remain open.” This is not permission to begin bulk cutting.

Revise and resample

Use when a change can affect fit, measurement, pattern, material behavior, construction, function, appearance or other product requirements. Identify the next sample stage and the exact evidence needed to close each issue.

Reject or return to the brief

Use when the sample follows the wrong concept, material platform, target fit or product requirement so extensively that patching individual comments would preserve the wrong direction. Confirm the revised brief before authorizing another round.

Administrative corrections that cannot change the physical product may be closed in the controlled documents. Do not use that exception for fit, fabric, artwork, label content, trim, packaging or test changes.

For a grip sock, add approvals for exact yarn/knit program, foot range, heel/toe/cuff or straps, grip compound and pigment, original sole artwork, deposit map and process, nominated reformer/mat/floor surfaces, internal orientation and after-wash retest. The grip sock manufacturing guide provides the two-interface evidence structure; “looks like the reference” is not a functional approval.

Ready Styles: a shorter order-confirmation checklist

Ready Styles use an existing standard pattern, fabric and construction. The buyer normally does not need proto, fit and grading development. After selecting style links from the private Excel file, confirm:

1. exact style ID and current product photographs;
2. whether finished stock is available or production is still required;
3. available colors, sizes and quantity by selected combination;
4. finished-garment size information for the standard product;
5. current stock quotation sheet and lead time;
6. any permitted logo, label or packaging option and its separate proof/MOQ;
7. order-confirmation sample, photographs or other evidence agreed for the selected lot;
8. final inspection or selected 100% checks appropriate to the actual order.

The garment MOQ starts from 50 pieces per style, with at least 15 pieces per selected color and size combination. Availability, price and branding feasibility are reconfirmed after selection.

Hi Jerry, please send the current Ready Styles Excel catalogue and stock quotation sheet. I am looking for ____. Estimated quantity: ____ pieces per style. Target market: ____. After I select the style links, please confirm available colors and sizes, finished-garment information, lead time, permitted branding and the approval evidence for the exact order.

Request the private Ready Styles files.

Full Custom: the PP sign-off package

Full Custom Manufacturing starts from 200 pieces per color and style. Before bulk cutting, use the activewear purchase order checklist to make sure one controlled package aligns:

• final purchase order and color/size breakdown;
• approved tech pack, BOM and pattern revision;
• approved measurement chart, grade and tolerances;
• final fabric, trims, colors and artwork;
• approved label and packaging files;
• closed sample-comment history;
• required test reports and their exact coverage;
• identified PP sample or sealed reference;
• bulk QC and final inspection plan.

Hi Jerry, I am developing a custom ____. Quantity: ____ pieces per color and style. Target market: ____. Current sample stage/round: ____. Please review the attached version-controlled tech pack, measurement report and numbered comments. My decision is ____. The next proof required is ____. Do not begin bulk cutting until the final PP sample and listed documents are aligned and approved in writing.

Start a Full Custom sample and PP review.

Sample approval does not replace bulk inspection

The approved PP sample defines what production should reproduce. It does not prove that every bulk unit will fall within specification. Incoming material checks, in-process controls, laboratory tests and final-lot inspection answer different questions.

Use the AQL 2.5 activewear inspection checklist to define the lot, sampling plan, defect classes, measurement checks and disposition. AQL 2.5 is not a substitute for the PP reference and is not permission to ship 2.5% defective garments.

For a tennis or exercise dress, turn the sample inside out and inspect the outer and inner systems separately, then repeat the agreed movement, pocket-object and bathroom-access protocols after care. The tennis dress manufacturing guide provides the product-specific fields and release gates.

For running shorts, inspect the shell, brief or long liner, split/hem, waistband, drawcord and storage inside out, then repeat the declared phone/fuel load, stride, chafe-observation and after-care protocol. The running shorts manufacturing guide provides the product-specific specification and release matrix.

For cycling bib shorts, verify the exact pad code, orientation, size mapping and placement before inspecting the lower seams, brace, grippers and cargo attachments. Then repeat the declared bike/saddle/posture, object-load, contact, opacity and after-care protocol from the cycling bib shorts manufacturing guide.

For golf polos, inspect the collar and support layers, neckline/stand, open and closed placket, closures, armhole/sleeves, tucked/untucked hem, vents and decoration before and after the agreed care route. Repeat the controlled address, backswing and follow-through sequence in risk sizes using the golf polo manufacturing guide.

For running jackets, inspect the exact shell stack, face/inside, seam and tape map, zipper ends and guards, hood/collar, vents, pocket bags and loads, cuffs, hem, adjusters, reflective details and self-stow route. Repeat the agreed movement, rain/wet, pack and after-care states from the running jacket manufacturing guide without treating a shell swatch report as complete-garment approval.

For a heavyweight hoodie, approve the exact body/rib articles, conditioned GSM, face/back and finish before checking the block, hood load, opening or zipper, rib attachment, pockets, seams, dye/wash range and decoration. Repeat dimensions, twist, zipper/rib/pocket appearance, surface and fit after the agreed care route using the heavyweight hoodie manufacturing guide; a swatch or mid-size fresh sample is not final approval.

For a heavyweight jogger, approve body/rib/elastic/drawcord/pocket identities before checking waist, rise/crotch, seat-to-hem line, pockets, cuff/open hem, seams, wash and decoration. Use the heavyweight jogger manufacturing guide to repeat dimensions, twist, waist/cuff entry and recovery, nominated-object pocket load, timed knee-flex recovery, surface, color and fit after the agreed care route.

Standards and source scope

This guide was reviewed on August 11, 2026 against the official ISO and ASTM pages linked above. Those sources describe test or classification methods. They do not provide one universal activewear fit, tolerance, color grade, seam-strength limit, wash limit or approval sequence. The buyer, product team, factory and appointed laboratory must select the applicable current method and product-specific acceptance criteria.

The checklist is practical sourcing guidance, not a claim that Linked Sourcing has tested every Ready Style, material, color or production lot to every method named here. Request the evidence that applies to the exact selected product and order.
