I bought my squeem about a week and a half ago in a size small,big mistake LOL. I should have bought a medium because the small was too small but I made it work anyway so ladies follow the size guide, dont't try to go down a size. Anway the first day I wore my squeem I wanted to scream it was killing my back because it was extremely tight,I only wore it for 2 hours that day. The next day I only wore it for about an hour and a half because my back was still raw from the day before. I was about to give up and just go order a medium, but then I thought maybe I should try wearing it to sleep being that the squeem only hurt when I would walk. I wore my squeem to bed the first night and everthing went well. I would take it off as soon as I wake up and continue with my daily activities. The next night it was even more comfortable then the night before. Now a week and a half later and I can visibly see a difference in my stomach. I will be on the 2nd clasp by the end of the week for sure. Now I have the perfect hour glass shape, and it is making my hips poke out more because my waist is shrinking. Soo ladies this doese work and I do recomend this squeem. Just remember follow the size guide and you should be fine.
