I purchased 8 pair of these wings. They are beautiful. They look like the jewel opal stone but not as white, when in the lights the iridescent pastel colors are amazing, and that is the studio light. I can only imagine how beautiful they will be on stage in professional lighting. The only negative thing to mention is on a couple of them at the bottom of the place you slide the stick in the stitches give way and the stick slides through. This is a easy fix, I just reinforced with extra stitching.
As far as the size to order. My dancers using these are 11 - 12 yrs of age. I wanted the wings long enough to go to the floor but not trip on. The Small adult is perfect. I am 5'4 and would order the M/L for my height.
