I got these last week for a Halloween costume and have worn them once so I can't comment on durability yet, but they are quite soft and comfortable and look like high quality. I'm 5'8, 124lbs and usually wear size Small (0, 2, or 4 depending on the brand), but I followed other reviewers and got these in Medium. They fit excellent in the waist and hips, no digging into the skin nor any wrinkling. As others have said, they're also not too low and don't show panty lines too much.

However, they are a bit loose on me in the knees, calves, and ankles and form wrinkles there, which is very strange as other reviewers say they are tight in the lower leg. My legs are sized and shaped much like the legs of the model in the main photo, and I don't see any wrinkling on her except a bit in the ankle so may be she is wearing the size Small, but I think if I were to get Small they'd be less well fitting and comfortable in the waist and hips, which is important esp when you sit down. So I decided to keep my Medium and just deal with not having it perfectly taut. Since this product qualifies for Free Returns, I'd order two sizes and just keep the better fitting one.
