Fit Guide

Nyssa's sizing is based on standard maternity sizing. If you wear a Medium in your maternity pants, we recommend you purchase a S/M of Fourthwear Underwear.

If you're between sizes (you sometimes wear a Medium and sometimes a Large) we recommend going with the smaller of the two sizes as Fourthwear Underwear is supremely stretchy.
