I own two Spanx total body shapers for which I wear a large. I ordered a large in this item and it was a total body workout to get it on. A large was way too small for me. I was able to actually get it up (although I had trouble breathing) and there is a seam down the front and the back of the suit. I do not like the seam, you can clearly see it through many of my shirts. It also has a built in tummy xtra control panel, and that was problematic for me as well - it caused lumps and bumps instead of the smooth figure that Spanx gives me. I was looking for a cheaper product than spanx with a spanx quality but this won't be it.
