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.

Love love love.
Review by Sarah K. on 25 May 2025 review stating Love love love.
I love all my Sarah sports bras! This one has mesh and I love that it feels extra breathable. Amazing support for running and high impact workouts. Also the phone pocket comes in clutch for runs as you don’t feel it when it’s in the sports bra.
