How to Run 3D Sample Approval Reviews Asynchronously

Learn which garment approvals a shared 3D view can move out of meetings, what needs physical checks, and how to run and measure asynchronous reviews.

Can a 3D clothing viewer reduce sample approval meetings?

• Yes, for decisions reviewers can make from the same agreed 3D garment view.
• CLO supports 2D pattern creation and editing alongside 3D garment simulation.
• CLO-SET is a separate collaboration and product-development platform that can be used with CLO for review and collaboration.
• Keep physical checks for material behavior, construction durability, and wearer comfort.
• Give every review round a defined decision, a named owner, a shared revision reference, and a closeout record.

A 3D garment viewer can move routine visual approvals out of meetings when every reviewer sees the same garment revision and answers a clearly bounded question. Teams can review silhouette, proportion, colorway direction, graphics, trim placement, and early simulated-fit questions asynchronously, then reserve live discussion for a decision that remains unresolved. CLO supports 2D pattern creation and editing alongside 3D garment simulation, while CLO-SET is a separate collaboration and product-development platform that can be used with CLO for review, collaboration, presentation, and product-development workflows.

The garment view and the approval process serve different purposes. The view gives reviewers a shared visual reference. A round brief, feedback standard, decision owner, and written closeout turn that reference into a review workflow. CLO Virtual Fashion has documented Uniteks presenting graded sizes online in 3D for initial approval, and TYH Textile using CLO for fit tests and CLO-SET turntable videos for customer presentations.

1. Decide which approvals can happen asynchronously

Route a decision to asynchronous review when reviewers can judge it from the agreed digital information, the acceptance criteria are clear, and a responsible person can consolidate the responses. A 3D view works well for questions about visible design intent, relative placement, proportion, and the garment’s appearance across the views and sizes included in the review. It gives the team a shared object to inspect without asking everyone to attend at the same time.

Use a physical check when the decision depends on an actual material, a sewn assembly, or a person wearing and moving in the garment. A digital review can identify questions for those checks and help the team focus the physical sample on the garment requirements that remain open.

In reporting on virtual prototyping, Apparel Resources described design-development and prototype samples as work often developed in 3D, while buyers continued to review fit samples physically. That reported practice supports a useful sequence: use digital review to narrow visual and design questions, and use physical review for the fit, movement, and material questions the team has specified.

A test method can make a physical gate more precise than a general request to “check the fabric.” The AATCC description of Test Method 135 covers dimensional changes in fabric after home laundering, while AATCC Test Method 150 addresses dimensional changes in garments after home laundering. AATCC Test Method 61 describes accelerated laundering tests for colorfastness of textiles expected to withstand frequent laundering. These methods address different sample questions, so the product team can select the one that matches the garment specification and approved test plan.

Construction requirements also need an evidence source suited to the assembly. ASTM’s D1683/D1683M method addresses failure in sewn seams of woven apparel fabrics and describes using seam and fabric breaking forces to determine seam efficiency. The AATCC Technical Supplement contents list procedures for apparel appearance after repeated home laundering and for pocket reinforcement strength. A team can use these categories to write the physical-check request in terms of a garment’s actual risk: for example, confirm pocket reinforcement on a loaded pocket, or assess appearance after the care cycle specified for a washable style.

Treat the table as a routing guide, then tie each physical check to the requirement the product must meet. A stretch knit top may need a wearer assessment for comfort and recovery, while a woven outer layer may need a seam-performance check and a movement assessment. A graphic placement approval can usually proceed on a 3D view even while a separate colorfastness test remains open. The team can therefore close visual decisions promptly and carry the specific material or construction question into its own physical gate.

2. Define the scope of each review round

A bounded review round asks for one decision against one identified garment state. Before inviting reviewers, write the question the round will answer, the acceptance criteria, the garment revision, the reviewers whose functions matter, the person who will close the round, and the point that triggers escalation. This gives each participant a clear task and keeps an approval request from turning into a general status meeting.

The Lifecycle PLM guide to fashion product development recommends naming the purpose of each round, linking it to the specification being reviewed, and issuing one consolidated decision. Apply that structure to an asynchronous round by putting the specification reference beside the 3D view. For example, “Approve shoulder and body proportion for the base and graded sizes against the current approved measurement table” is more actionable than “Please review the style.”

Use this round brief before the invite goes out:

• Decision: State one approval or revision question, such as silhouette direction, pocket placement, artwork scale, or graded-size appearance.
• Review reference: Identify the style, colorway, sample stage, revision label, date, and the 3D view or supporting specification used for the decision.
• Acceptance criteria: Describe what an acceptable result looks like, using the measurement, placement, reference image, or approved specification that applies.
• Review scope: Name the views, sizes, components, and questions included in this round. A size-set review, for example, should state which sizes reviewers will inspect.
• Required functions: Invite people who own relevant decisions. A visual design round may need design and merchandising; a construction or material round may need technical design, sourcing, production, or quality assurance.
• Decision owner: Name one person who will reconcile feedback, record the outcome, and assign any follow-up.
• Response window: Give a start and end time, plus the time zone for a distributed team. Set the interval around the stage deadline and reviewers’ work patterns.
• Escalation trigger: State the condition for a live conversation, such as conflicting instructions, a criterion that needs clarification, or a decision that depends on a physical result.

A pre-production sample review is a distinct kind of gate with downstream production consequences. UpHance’s guide to pre-production sample review describes checking the final sample before bulk against the approved tech pack, graded specifications, approved trims, and approved lab dips. It also identifies technical design, production, merchandising, and often quality assurance as participants, with a consolidated result such as approval, approval with comments, or rejection with required revisions. Teams can use that example to distinguish an exploratory design review from a production sign-off that needs evidence against a fixed specification.

The decision criteria should match the decision’s stage. In an early concept round, acceptance might mean that the silhouette and design details align with the approved sketch. In a fit-development round, it might mean that the reviewed measurements and simulated shape identify the next pattern changes, with physical fit evidence assigned where required. At a pre-production gate, the criteria should name the approved technical pack, material references, construction details, and any required test or wearer results.

A bounded round can still gather broad expertise. Ask each function to comment on its defined responsibility, then ask the decision owner to synthesize the responses against the acceptance criteria. This makes the owner’s job a decision task, rather than a clerical task of collecting unranked opinions. It also gives reviewers a reason to respond asynchronously: they know the decision they are contributing to and when their input is due.

3. Keep every reviewer on the same garment revision

Version clarity starts with a stable reference that travels with the review invitation and each response. Give the round a unique label, identify the style and revision, and state which saved garment view and supporting specification reviewers should use. If the review contains graded sizes, name the sizes and the size-specific views included. A comment about a sleeve or hem can then be interpreted against the same revision by design, technical design, merchandising, and production.

A useful way to set up the review is:

1. Create the round record. Add the style name or identifier, review purpose, revision label, review date, response deadline, and decision owner to the review log your team uses.
2. Identify the artifact. Point reviewers to the exact garment view or asset prepared for this round. Include the colorway, size or size set, and any relevant measurement table or approved specification.
3. Changes since the last decision. Summarize the pattern, material, trim, or design changes since the previous decision. Name any assumption that affects the view, such as the fabric option represented or the size being assessed.
4. Freeze the round reference. Keep the invite, comment log, and closeout record tied to the same revision label. When a new revision enters the review, start a new round reference and carry forward only decisions that remain applicable.
5. Confirm the open question. Ask reviewers to respond to the stated criterion, not to an earlier attachment, an old email, or a different size view.

The CLO Help Center’s Save 3D State guide for Review Mode explains saving simulated 3D states for each graded size and applying them in Grading Review mode. That provides a size-specific visual review option inside CLO. Cross-functional rounds still benefit from an explicit style and revision reference in the team’s review log, so the decision stays connected to the correct garment state.

For a first pilot, a simple naming convention is enough to improve shared context. For example, use a label such as “Jacket-042 / fit review / revision C / sizes S–XL / 09/30/2026.” Keep the naming pattern stable across rounds and store the linked acceptance criteria with it. A later reviewer can then distinguish a fresh decision from a comment carried forward from a prior revision.

4. Make asynchronous feedback actionable

A useful comment tells the owner where to look, what the reviewer observed, why it matters to the round’s criterion, and what action or decision is requested. “Sleeve looks off” names a concern without locating it or describing the expected result. “At the front view, the sleeve opening appears wider than the approved measurement reference; confirm the target circumference for size M” gives the owner a location, observation, reference, and next decision.

Use a consistent feedback format in the channel your team already works in:

• Location: Identify the garment area, view, size, or specification line.
• Observation: Describe what appears in the current revision, using specific words such as “hem is 2 cm above the reference” when the measurement applies.
• Reference: Name the design, measurement, construction detail, or material requirement used to judge it.
• Request: State the requested change or the question that needs an answer.
• Priority: Mark whether the item blocks this round’s decision, needs a later physical check, or is an optional refinement.
• Owner: Identify who can answer or implement the request.

Keep one comment focused on one issue. If one note asks for a longer sleeve, a different neckline, and new artwork placement, the owner cannot tell which change satisfies which criterion. Separate those requests and identify their priorities. When a comment concerns a physical property, label the evidence needed to resolve it, such as a fabric hand assessment, wear trial, laundering test, or seam-performance check.

The round owner should acknowledge comments that need interpretation and request a more precise observation while the review is open. A reviewer who sees a possible balance issue can say whether it concerns visual proportion, measured balance, or a fit observation on a wearer. That distinction routes the comment to the right function and evidence. The reviewer can also attach a reference image or measurement point when the team’s review channel allows it, or identify the precise view and reference in text.

CLO’s 2D pattern and 3D simulation capabilities give the design team connected garment-development context for reviewing pattern-driven shape questions. CLO-SET provides a separate collaboration setting for review and presentation. Keep the feedback template as the team’s standard, and use the currently approved review channel to capture each comment with its garment revision. This workflow makes feedback portable across functions, whether a comment concerns a visible design detail, a pattern adjustment, or an item assigned to physical validation.

A helpful review prompt might read: “For revision C, review the back neck width in size M against measurement spec 14. If the displayed width differs from the target, state the view and measurement reference, and recommend the adjustment. Fit comfort remains assigned to the wearer check.” Reviewers can answer independently, and the owner can compare their responses against the same criterion.

5. Give one person responsibility for closing the round

A review closes when the team has one recorded disposition for the stated question and a clear next action for every unresolved item. Name the decision owner when the round opens. The owner groups comments by decision, resolves compatible requests, assigns changes, records the disposition against the reviewed revision, and routes any physical-validation result to the next gate.

For ordinary design questions, an owner can consolidate feedback after the response window and issue a result such as approved, approved with specified revisions, or revise and review again. Use the terms consistently across teams. “Approved with revisions” should name the exact change, the person responsible, and whether the updated result needs another review. A recorded result helps the next function know which visual decision is settled and which action remains open.

A pre-production review often has a more formal closeout. UpHance’s pre-production review guide describes corrections becoming a pending tech-pack revision, followed by production review and written acknowledgment of the corrected revision. It also describes the pre-production sample review as a gate before bulk cutting. That example shows why production sign-off needs the approved specification and the revised document linked to the outcome, rather than an informal statement that the sample “looks good.”

When functions disagree, the owner first identifies whether the disagreement concerns a shared criterion or competing business requirements. If design requests one proportion and merchandising requests another, the owner identifies the trade-off, the decision-maker with authority for the product direction, and the deadline for the decision. If the conflict depends on wear, material performance, or construction evidence, route it to the physical gate and record the result as a separate input.

A live meeting earns its place when it resolves an issue that comments cannot settle efficiently. The owner can call a focused meeting with only the functions needed, state the contested criterion in the invite, and end with one recorded disposition, owner, and due date. Reviewers who have already supplied clear comments do not need to repeat their full review in the meeting. This exception-based approach protects asynchronous review for routine decisions while keeping a direct path for material conflicts.

The team’s assigned decision owner remains responsible for its approval protocol. Record the final decision in the team’s designated project record with the revision label, date, decision, conditions, unresolved physical checks, and person responsible for each follow-up. This leaves a clear link between what the team saw, what it decided, and what still requires evidence.

6. Put the physical-check gate where the evidence is needed

A physical gate should answer a named question that the 3D review cannot settle by visual inspection alone. At round closeout, identify the property, sample or test needed, responsible function, acceptance criteria, and decision date. Link the result to the same style and revision reference used by the digital review. This keeps a physical check focused and gives reviewers a clear route from a digital observation to the evidence that resolves it.

Use these steps to define the gate:

1. Name the unresolved property. Examples include hand feel, stretch recovery, movement drape, garment dimensions after washing, laundering colorfastness, seam strength, trim durability, or wearer comfort.
2. Choose the evidence. Select the product’s existing quality method, laboratory test, construction inspection, or wearer assessment that matches the requirement. State the sample, fabric or trim lot when relevant, test or wear condition, and acceptance limit.
3. Assign the work. Name the function or person arranging the sample and checking the result. Set a due date that connects to the development milestone.
4. Record the result against the revision. Capture the observation or test result, the applicable requirement, and whether the criterion is met.
5. Close or reopen the decision. Close the physical question when the result meets the agreed criterion. If a result triggers a change, identify the new revision and return only the affected decision to review.

For a woven seam, name the fabric and seam assembly under review, then tie the measured seam result to the product’s stated acceptance criterion. For post-laundering appearance, state the care cycle and the garment feature the team will inspect after the sample completes it.

Wearer comfort and movement need a wearer-based assessment when those are product requirements. State who will wear the sample, which size or fit model is involved, what movements or use conditions they will assess, and which observation criteria apply. A simulated view can help the team identify a potential issue and prepare a focused wear review.

A physical gate can run in parallel with visual approval when the open questions are independent. For example, a team can approve graphic placement asynchronously while a laboratory evaluates laundering colorfastness. The graphic decision closes on the reviewed visual revision; the color performance decision closes on the test result. If a test result requires a colorway or material change, the owner opens a new, clearly labeled review for the affected appearance decision.

7. Measure whether the workflow changes meeting load

A pilot should measure both the intended change and the work needed to achieve it. Establish a baseline for comparable styles or review rounds before the pilot, then record the same measures during the pilot. Track meeting count and duration, round completion time, number of physical sample rounds, reopened decisions, and conflicts escalated to live discussion. Add context such as style category, review stage, number of sizes, reviewer functions, and whether a physical test was required.

The U.K. Treasury’s guidance on policy impact evaluation describes a before-and-after design as measuring the situation before an intervention and comparing it with later measurements. It explains that this type of baseline can show change over time, while a comparison group helps assess what might have happened without the intervention. For a practical team pilot, that means a before-and-after count can tell you whether meeting load changed during the rollout; a comparable group or staggered rollout can make attribution more informative.

Use a pilot scorecard with consistent definitions:

Compare similar work with similar work. A straightforward visual design review and a pre-production sample gate answer different questions, so combine neither into a single average without separating stage and product type. A jacket with a required movement test and a printed T-shirt with an artwork-placement review also carry different physical-validation needs. Compare the same kinds of review rounds before and during the pilot, and record any change in staffing, calendar pressure, or product mix that could affect the result.

The first pilot can use one product category, a defined stage, and a small set of recurring approval questions. Record the baseline from recent comparable rounds, then use the new review brief, version label, feedback template, and closeout record. At the end, compare the measures and review a few individual rounds to understand why numbers changed. Fewer meetings alongside longer completion times, repeated reopened decisions, or extra coordination effort suggests the team should adjust the process before expanding it.

As an illustrative hypothetical, a pilot report could say, “Routine review meetings fell across comparable silhouette rounds, while physical sample rounds stayed stable.”

8. Turn the pilot into a repeatable review practice

After the pilot, keep the practices that improve clarity and revise the ones that create extra work. Use the meeting and round data together with comments from reviewers and owners. Ask whether each decision had a usable reference, whether reviewers knew the revision, whether the stated acceptance criteria resolved comments, and whether the owner could close the round on schedule. Keep a physical gate whenever the garment requirement depends on physical evidence.

Expand by decision type, not by a blanket rule that every sample approval belongs online. A category with frequent visual revisions and stable criteria may be ready for asynchronous rounds at design development. A fit approval involving movement, recovery, or wearer comfort may still need a physical assessment. A pre-production sign-off can combine an asynchronous review of documented details with the physical checks specified by the product’s quality process.

For each new review category, pilot the same basic controls: a named decision, stable garment revision, relevant acceptance criteria, defined reviewers, one owner, a response window, an escalation trigger, and an evidence-based physical gate where required. Use pilot results to assign defined visual approvals to asynchronous review, retain physical gates for requirements that need physical evidence, and reserve live coordination for unresolved decisions. Explore CLO for its garment-design workflow and read the CLO Manual for current product instructions.

Frequently asked questions

Can a 3D clothing viewer help reduce sample approval meetings?

Yes. It can support asynchronous approval of decisions that reviewers can judge from the same garment revision and agreed visual criteria, while a named owner gathers feedback and records the outcome.

Which garment decisions should stay physical?

Fabric hand, stretch recovery, movement drape, wash and shrinkage behavior, seam or trim durability, and wearer comfort need physical confirmation when those properties are part of the product requirements. Use the quality plan or specified test method that matches each question.

Does CLO include CLO-SET?

No. CLO and CLO-SET are separate products. CLO supports 2D pattern creation and editing alongside 3D garment simulation; CLO-SET is a separate collaboration and product-development platform that can be used with CLO.

How do we keep comments attached to the right revision?

Give every round a style identifier, revision label, review purpose, date, size or size set, and one link to its review reference. Ask reviewers to include the same label in comments and record the closeout against it.

How can we tell if the process worked?

Compare the same measures before and during a defined pilot: approval-meeting count and duration, review-round completion, physical sample rounds, reopened decisions, and live escalations. Report the product categories and review stages included in the result.
