I’m 5ft 165 lbs and got a size large. It fits, you just have to make sure you step into it. The one thing I don’t like is that it flattens your butt. Wrong thing to flatten! Everything else feels fine.

I ordered a XL and it doesn't shape or fit my breast like the picture. I have 38DDs and my boobs hung out. It was like an under breast line/body slip.
