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?

Our Performance Innerwear is engineered to contour and respond to your shape, creating a personalized fit that evolves with wear. Designed to retain its integrity, it will mold to your body. As with any high-performance knit, sizing down places additional tension on the fabric, and over time, the nylon fibers will naturally relax.

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.
