First of all, size up! I'm 130 and 5'6" with an average build. Normally I wear either a 4 or 6 in pants, and a large in these proved to be perfect. They do have a sheer quality before you put them on, but if you can't see my blinding white skin then everyone else should be safe. I was pleasantly surprised that these cover my whole butt and gave some length past the crotch. Basically these are exactly what I was looking for to take to music festivals with me. Highly recommend
