I'm a bigger girl. I read the reviews and I figured I would go with a 4x. I wear a 24-26 in pants and these 26-28 bottoms was tight but they did go on. The top fits wonderfully and I'm ok with the bottoms not fitting I can wear shorts which I prefer anyway. I mostly wanted the top so I could stop wearing a t-shirt in the pool. Hopefully with all the added exercise the bottoms will fit in no time.
