I have this in a grassy green color, and it's among my favorite leotards. It does run fairly small... I'm 4'11" and about 105 lbs (I have a bit of a derriere), and I needed a medium. The hip and sleeves run small; I'm usually a size small, but my shoulders were too tightly squeezed in the tank. The openings for my legs were also too tight in the small, and I found it very uncomfortable and distracting. However, the medium fits me like a glove.
The iridescence is lovely and accentuates your lines in the best way. The bust is also beautiful; I'm flat chested, and this leotard provides the illusion of curves. I've had this leotard for 2 years, and there's no evidence of wear or tear aside from the tag falling off a little. Most definitely worth your while!
All the colors are very pretty :) I own it in red. The neckline and back are very pretty and flattering, I just wish the leg line was a bit higher. I'm 5'3'' 100 lbs, and I fit into both a Small and a Medium. I bought the medium just so it would still fit if I grow a bit. I don't think the leg line would bother me as much if I had gotten the small instead, because the torso would be tighter. But definitely very pretty :) The material is soft and an interesting texture which I personally like. Good quality. No rips or tears or anything and I've owned this leo for over a year.
