I bought this for my dysphoria, and it helps a bit, not much though since the sizes are too big!! I was a 36 a when I bought this (I'm a 34 a now) and ordered a medium as suggested and it barely had any effect. It was a nice buy to help a little though! The clasps aren't too sturdy either, I have a friend who bought one as well and they have a bigger chest area and the upper clasps kept unhooking once they sat down or twisted their upper body.
