If your hips are wider than your chest, use your hip measurement in place of chest measurement.

**Please note: Our sizing has changed slightly. We used customer feedback and sales data to track how best to size our garments. Please double check the measurements listed here against your existing BUON pieces if you have shopped with us previously.**

Measurements are approximate, and rounded down to the nearest whole number.
