Direct answer

Approve the base size on a documented fit model, then review the grade rules for coverage, support and tension—not only proportional measurements. Confirm selected edge sizes before bulk when risk is high.

Fix the fit reference

Record the base-size body measurements, garment measurements and fabric used. Changing fit models or fabric between rounds makes feedback hard to interpret.

Review negative ease deliberately

Swimwear is often smaller than the body because stretch creates fit and support. The amount should reflect fabric recovery, silhouette and target comfort.

Grade structure as well as outline

Cup position, strap length, elastic tension, gusset, rise and leg opening may need specific rules. A simple scale-up can distort support and coverage.

Check risk sizes

For a broad size range or structured product, confirm more than the base size. Prioritize sizes where support components, torso length or coverage change most.

Is ‘make it more supportive’ enough?

No. Identify the size, location and movement involved. Include the intended result and images or measurements so pattern, lining, elastic and strap options can be evaluated.

Should the factory receive comments from every stakeholder separately?

Consolidate comments first. Resolve conflicting preferences and make clear which details are approved before requesting the next version.
