Sports Bra Size Chart

BUST
Measure your bust circumference at its fullest point, wearing a bra without padding. Stand with feet hip-distance apart and find the widest part around your bust. Keep the measuring tape parallel to the ground and try not to pull the tape too tight - it should not indent the skin.
BAND
Measure the circumference under your bust, around the rib cage where the elastic band of a sports bra would land. Be sure you do not "flare" your rib cage or suck in your breath. Keep the measuring tape parallel to the ground and try not to pull the tape too tight - it should not indent the skin.
Note: If the chart gives you two size options, we recommend to go with the smaller size for a more supportive fit and the larger size for a more relaxed fit. This guide provides general sizing information, which can vary depending on style.

Great pattern
Review by Kelly B. on 27 May 2025 review stating Great pattern
Love this pattern. Sarah bras are a staple for running, with the handy back pocket and smooth band around the rib cage. Sizing is somewhat inconsistent- I wear a medium in some and small in others. I’m a small in most other sports bras.

It’s great! Love it. I like the skinnier bottom band than my older Sarah bras.
