Pre-preg I’m typically an XS/S and the S/M fits my second trimester bump great with room to stretch! It’s super comfortable (good butt coverage) and very flattering even though there is no padding. This is my 5th pregnancy, and I know this suit will be perfect for chasing around all my other kids on our beach vacation! Shipping time was kinda long. I waited about 2 weeks for my order to arrive, but if I had time I would order another for sure!
