I like this swim dress. It's comfortable and fits mostly well. The ruching is very cute and flattering and the attachable bands to the swim leggings are very convenient.
The only problem is that the swim dress's arms are skin tight on me. I found it a difficult to put the dress on because of the tight arms and shoulders. Because of this, I was worried the dress wasn't going to fit well, but luckily aside the arms it fit slightly loosely as shown in the images.
I'm 5ft, 2in. with a 35" bust and 27" waist, US size 4-6 (UK size 8-10) similar to the model shown.
