I am a size 2-4 and always wear a size small or extra small. I ordered a small in this and it was way too tight across my butt/hips. I have a curvy petite figure so if I had a flat butt and no hips this would have worked much better. Even up top, I'm a 34C, it was tight. Also, I could see my underwear through it a little. I think if I wore nude underwear it would have worked fine because the fabric is thick enough it seemed. The colors were really pretty too. Just sizing it not really meant for curves I guess.
