Your body is perfect just the way it is.

The numbers below are simply there to help you find the right fit with FITSO. We've worked since 2016 to develop our sizes based on real people, and stretch test our garments to determine the sweet spot between support and comfort.

FITSO garments fit like a hug, not a squeeze! This generally gives a 40-50% stretch in all of our garments, so if you prefer a tighter fit we recommend sizing down.

We do not follow the vanity sizing standards of the fashion industry at large. As a result, we may sometimes make changes to our sizing and encourage regular feedback about the fit from all our customers. Send an email with your thoughts or questions about sizing to
