This is a cute pattern which is why I bought this. Bottoms fit big. Not as cheeky as I would like and comes up back too high for my liking. I bought XS but on larger side for me based on the fit I like.

The top fit perfectly, but the bottoms were way too tight. I ordered large and it looked like a medium. Was hard to put on so just make sure to size up. Mix and match sizes should be incorporated to help with this.
