I bought this in both blue and black. I'm 5'7", 135 lbs, with a shorter torso and I ordered Mediums. They both fit perfectly. With high rise leggings, the only skin that shows for me is where the slit is. With mid-rise leggings, I do have a little more belly showing, but not much. Very silky, stretchy, and breathable. They feel nice on the skin and look cute whether you wear them with the slit in the front or back.
