Size Guide

O.Y.B pieces are designed with shape, proportion, and movement in mind. Some garments are intentionally oversized, adjustable, or designed to sit differently on the body depending on how they are worn.

Please refer to the individual product page for specific garment measurements where available.

Fit Notes

Some O.Y.B garments are cut with volume, adjustable details, or deliberately shifting silhouettes. If you are between sizes, we recommend choosing based on your preferred fit.

For a closer fit, choose your usual size.

For a more relaxed or oversized fit, size up.
