What Should Be Done When a Sample Fits but Fails Fabric Testing?

A fit-approved sample that fails fabric requirements still needs correction before production release.

Use the intended production fabric and construction for decisions that depend on stretch, recovery, shrinkage, or seam behavior. A substitute can support early development, but it cannot reliably validate every performance requirement of the final garment without further confirmation and testing. Revalidate fit if the replacement material behaves differently.
