I ordered the top in black and size small. It fits well. It may be tight for someone who's busty because it doesn't stretch a lot. I suggest washing by hand or at least turning it inside out and washing on a gentle cycle. I also suggest hanging it to dry.
I ordered this top for a Showcase piece coming up. I tried it on and it isn't itchy or restrictive. I am not big up top but I don't feel any risks of it showing anything. It is lightly lined. I look forward to using this in future performances.
My daughter is eleven, bought it for her. Just chose the size according to what she normally wears in dance wear. Fits perfect and is comfortable. Bought this bra top as part of a competition outfit but could easily be worn everyday to class.
