I was little skeptical about buying a product such as this. But after 2 c-sections, and terrible eating habits, my tum has gotten out of control. I ordered a large, I’m 5ft 4in, 198lbs. When it first came in I thought it wouldn’t fit, but it does have a good stretch, so it did fit perfectly. I also have a very long waist, and the length fit perfectly which is a hard thing to achieve for me. I wear it for 2 hours a day while working around the house, and it makes me sweat!! I can actually see and feel the difference after every use. And it has fantastic lower back support, which is great for house work.For the mamas: If your bladder was ruined by your babies, like mine has, be prepared to pee your pants if you sneeze. There is no avoiding it. I wear my wrap with the bottom right at my c-section scar, as this is where the post pregnancy pooch starts (Bikini line incision), and it’s very comfortable in this position. I’m very excited to see the results with a healthy diet and exercise. You won’t be disappointed.
