How to measure
- Under bust. Measure snugly around your ribcage, right under the bust, keeping the tape level. Match that number to the first table.
- Between two sizes? The under-bust measurement decides. If it sits right on the line, take the larger size for a softer fit.
Band numbers are US, UK and Canada sizing, with the European and Australian equivalents underneath. Cups A to D share the same letter in all of them.
Sewn-In Pads, Seamless Support
Finally, a sports bra that actually supports without the struggle. The Racerback Sports Bra lifts, smooths, and shapes while keeping you cool and comfortable through every move.
Made from lightweight, breathable fabric with sewn-in pads that never shift, this bra delivers full coverage and lasting support—without wires or discomfort.
Its thick straps and racerback design relieve pressure from your shoulders and back, giving you a secure, confident fit that feels as good as it looks.
