What Are the Key Fit Points for a Racerback Sports Bra?

Racerback fit checks include underband stability, bust containment, armholes, and strap pressure.

A useful fit assessment checks comfort, coverage, stability, and movement in the intended activity. Record where the issue occurs and whether it changes after repeated movement or washing, then adjust the relevant pattern, material, or construction variable systematically. Observe movement rather than assessing standing appearance alone.
