I LOVE spandex material and the more of it the better. These are comfortable and supportive. So much so that I am going to wear them to the gym as cycle shorts. Quite a high sheen means all contours are on show.
These are a size LARGE and fit more like a medium so be careful when selecting your size.
For me these are A MATCH MADE IN HEAVEN. Gym suitable, underwear suitable and very sexy.
