Washable undies are designed to fit snugly, so they stay in place and feel secure. If you’re between sizes or prefer a roomier fit, we recommend sizing up for comfort.

We suggest measuring a pair of undies you already own (laid flat) and comparing it to our guide below, just to be sure.

All measurements are taken laid flat (then doubled).
