Size Guide

size guide


To find your band size, wear your best-fitting, non-padded bra and run a measuring tape below your shoulder blades and around the top of your bust, like in Line 1. Next, measure yourself again but around the fullest part of your bust, like in Line 2. Then, subtract Line 1 from Line 2 and use the difference in inches to find your cup size below. Use both your band and cup size to find your Bombas Bralette size. If your band size is an odd number, go up to the next even number. If you’re in between sizes, we recommend sizing up.

Women’s Underwear

Fit Details

We designed our underwear to feel not-too-tight, not-to-loose, but barely-there on your skin. Depending on the fabric of the underwear, you may want to size up or down if you’re between sizes. For Seamless Underwear, size down if you’re between sizes. For Cotton Modal and No Show Underwear, size up if you’re between sizes.
