I ordered this in the size recommended for my measurements and it doesn't do much. It does stay in place pretty well compared to similar products, but it doesn't really hold anything in. It's not tight enough to. I wore it around when I got it for several hours because I forgot I was wearing it... If you have loose skin, this might smooth it out for you, but for more solid  imperfections - like muffin top, it doesn't help- at least for me.
