What Causes Sports Bra Underbands to Twist After Washing?

Twisted underbands can result from elastic behavior, uneven application, shrinkage, or construction imbalance.

Changes to bra materials or assembly may invalidate earlier fit decisions. Confirm recovery, dimensional stability, and component behavior after relevant use and care, then document any required pattern adjustments; a visually similar substitute should not automatically inherit approval from the original development sample. Compare components before and after care.
