I LOVE this leotard so much, I am going to buy another one. For a one size fits all, I was skeptical, but it fits better than any leotard I have ever worn, and no wedgie!
I have it on right now and it is super comfortable under anything. You cannot beat this price either. I would order at least one of these while they are available.
There is now white and nude that was not available when I ordered.

The fit is just amazing, you do not even feel like you are wearing anything. The person that said you have to wear it under something is incorrect. I wore a black Victoria Secret bra under mine, with jeans and a belt it looked fine.
If you do wear it under "anything", you really do not need to wear a bra, there is decent support and I am a 36-C.

The sleeves are a bit shorter than Capezio (I ordered (3) of those as well) but that is fine. I pretty much like 3/4 length sleeves since I am cooking a lot, so the sleeves are never in my way! I find that to be a plus~
