I just purchased this and haven't yet got it wet so I'm just reviewing based on it being right out of the box. I was surprised this suit fit. I typically have to wear a different size bottom than the top but this one fits. I am 5'1 and about 105lbs and am about a 32 B.  I bought a Small in black. It fits great. I am on the petite side so maybe this suit runs smalls as others have mentioned? The bottoms aren't saggy but they aren't too tight. Same for the top. It's simple but stylish. It's not totally full coverage bottom but your butt doesn't hang out either if that makes sense. I walked around the house in and it stayed in place. A lot of suits ride up your crack when you walk. I may have to buy this in another color.
