I'm usually a maternity large (size 14 pre-pregnancy), but after reading reviews I got the 2X. They're pretty comfy without being too low in the front. They actually cover my booty without riding up. These might stay even after baby. I will note that I ordered a set of the lace trim version and am not as happy with the fit. Too low cut and not enough front coverage in general. They also seem to be a little smaller.
