It's fine.  It will be a good layering piece.  It's a very, very thin material.  Like, you know when your just hitting puberty, and you don't really have any boobs, but you want to wear a bra, but your mom doesn't want to have to buy you an actual bra yet because she wants you to be a baby forever, so she buys you some crappy sports bra instead, and it's pretty much like wearing nothing, because if you did happen to have boobs it wouldn't have supported anything or held anything in place, its basically just covering them with an extra layer of material.  That is this.  It's super thin spandex, basically un-supportive sports bra.  But the color is super fun and it'll be great under stuff or whatever.  And in case this wasn't obvious, you must wear some sort of bra underneath(if you don't want to show nip).
