I bought a few body con dresses & bought these to wear under them since my butt is absolutely flat. There is a gap at the bottom of the leg in these which makes it obvious that you're wearing them but I wear them under my shapewear & you cant see the gap at all. They still make my butt appear larger even under the shapewear. I would have given them 5 stars if not for the gap by the leg but they work for my purposes under the shapewear so Im happy.
