There is a zipper in the back and no stretch to this. I usually wear a size medium, but I got xlarge on purpose because I knew it was going to be short. But it has a pretty pattern and the fabric although it really is cheap and probably flammable. It’s decent and very light for hot weather. I am 53 135 pounds with a juicy butt and I got an extra large so that it was more loose fitting like for shopping with flip-flops
