Genetically, I was blessed with a beautifully full bum and unfortunately the sizing on this product does not coincide with the measurements on the description. This would easily fit a small and medium, but not a large or even an extra large. They do stretch so getting them up is not a problem, but they squish my goodies, making it appear very flat and I personally love my bubble butt, the last thing I want to do is hide it. I feel if i bend down too quickly, they might split open, so I am gifting this to someone who could use this.
