Size Guide

Measure around your underbust and use your cup size to determine your Su & So sports bra size. If you fluctuate between cup sizes, select the smallest one. You can also use the flat measurements in the second table to compare with existing sports bras you may have.

The following measurements refer to the flat, unstretched measurements of the sports bras when laying flat on a surface. For bras with adjustable underbusts, these measurements refer to when the bra is on the tightest setting.
