Which Sample Measurements Are Most Sensitive to Fabric Stretch?

Circumferences, waistbands, openings, and measurements under tension are particularly sensitive to stretch conditions.

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. Specify relaxation and applied tension before measuring.
