Tell me about fit:
Our Essential Racerback Sports Bra is designed to fit snugly against your body for maximum support. To find your best fit, start with the band—our sizing is based on field testing where two fingers fit comfortably between the band and your body, but not more.
How to measure your band size:
-
Measure snugly around your rib cage, directly under your bust.
-
Add 3 inches to that measurement.
-
Example: A 31" rib cage + 3 = 34, so your band size is 34.
-
-
If the result is an odd number, round UP to the next even band size.
-
Example: A 32" rib cage + 3 = 35 → round up to 36.

Our Performance Innerwear is meant to feel snug. If you prefer a slightly looser fit, we recommend sizing up. If it feels just a bit tight, try wearing and washing it a few times—most bras gently relax and mold to your body over time before considering an exchange.
Will it stretch out?
Yes! Performance Innerwear is designed to give a little with wear and washing, molding to your shape while keeping support and comfort.
