It's no use. You know this is meat, not mud. You can pinch it any way you want. If you want to lose weight, you can only lose weight. Isn't it easy to lose weight just by tying it? Also, some corset underwear will do harm to the body, and some materials are not good, which will cause allergies and other symptoms. So to sum up, it is best not to wear it and do more waist exercises!
