This leotard is lovely and comfortable. It is my daughter's favorite and her second most flattering. My favorite (what would be hers) is the three quarter length sleeve with open back with pinch front by Motionwear that is similar, but it is not lined. The adult MW version has a shelf bra which bunches on her and look ridiculous and the other doesn't cover well enough, so she won't wear it. That one is offered in a large number of colors, so having only 2 non-black options in this style is a disappointment and she thinks the color options are babyish (she's 12).
This has a full front liner, which she loves. The only improvements I would make to it is to have a little higher cut leg to lengthen that line and to offer it in more colors - especially darker ones.
