I got a medium because my boobs are usually too big to fit into smalls. I am 5'4 and 125 lbs and I wear a 32 DD. The top was okay just a little looser than I'd like but the bottoms just fit me super weird. Might wear the top but I don't know about the bottoms
This is my fave suit right now, I love the color and the fit, the back straps go up pretty high which can be a little awkward but not uncomfortable, I'm about 5' 6" and 130 ish lbs, I'm 36 D and a size 4 in pants
Due to a lot of positive reviews I have this suit a try and ordered it. The adjustable straps and the padding are pluses! Color is beautiful! I am 5'4" 116 lbs and between an A cup and B cup. (I wear 32B in Victoria's Secret). Not a huge fan of the way the bottoms make my butt look due to the shape of the bottoms, but it's not bad and I still wear them! Although, I do like to pair the top with different bottoms sometimes too.
