Tell me more about the fit

Our Performance Innerwear is meant to fit snugly on the body. If you prefer a looser fit, we recommend sizing up. If it feels just a little tight and you aren't sure if the next size up would be better, we recommend wearing and washing it a few times to see if it breaks in to your liking before exchanging it for another size.

Will it stretch out?

Not really.  Our Performance Innerwear does give a bit with wear, but instead of becoming loose, it will mold to your body more over time. 

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.
