I did not have surgery and won't. I was looking for something to help on my workout journey. This totally works to tighten and shape. As I lose weight, I'm excited to see more of the shape show. Totally worth the purchase. I'm 5'3" 220 lbs. I got the 2XL and that is what is shown in the pics. I also purchased an XL to keep on hand for when I lose more weight and the 2XL becomes too big. It is comfortable, I do not sweat in it. The compression seems nice and tight. Those poor hooks are holding on for dear life! Lol! Good luck on your journey and this brand is definitely a great one to try. I am happy that I did based off of a recommendation from my sister in law. Left pic is without it on. Right pic is with it on.... In the 3 pics shown.
