My thighs were so bad that I knew there was going to be a big change. So I used the size of my hips to judge the size. I hadn't realized that the doc was also going to do large volume lipo of my outer thighs - love that he did do it. So I measured my hips and went one size down. In the initial recovery, with the swelling, they were fine. However, towards the end, they kept riding down when I moved around. When I had my revision, I went yet a size smaller and they fit like a glove. You will probably have to take them into the or and they will put them on you right after the surgery. I had to get the garment that went right below the knee - capri length. They are tough to get on - for the first few days, I needed the help of my husband to get them zipped and hooked up. The first few days are also interesting dealing with them and the drains but you will figure that out quickly.

You don't see the closures in the pictures, but there are hooks and eyes first, then a zipper that runs up. They're very secure and we'll made. And you'll have a real love/hate relationship with them. They're uncomfortable as hell when you're swelling, but also make you feel like your skin isn't going to explode open. Mine was put on while still in the OR. I also never used anything but the stage one. Don't know what the difference is between the one and the two.
