This is really smooth and seamless, which I like. It reminds me a lot of nylons in how it works with your body. Yes, when you sit down it does crease in and cause a little roll above the waistband similar to nylons. This is because it doesn't come all the way up to your rib cage (or a least mine, I am very long-torsoed). It wasn't super obvious, but it would be better if it was higher. The thong part is decently comfortable and it does actually pull in your tummy and flatten it out a little bit. My pooch was a lot smoother and pulled in a little bit, but I would have like a little more sucking power. I am going to try a size down to see if that helps, but if not I am going to keep looking for a firm control one, or a comparable one but with a higher waist. If I find that I will return this one.

UPDATE: the one at Victoria's Secret is WAY better so I am returning this one.
