What colour tutu should I get?

Personally I would pick the pink one but that's only because I completely love pink, If you love green and that's the one you want go for that as that one is gorgeous too and you are going to feel confident if you like what you are wearing, however if you are thinking practically, if tutu's can be practical :) then the black and white one can probably be worn with more colours as it is quite plain in itself, but then that can be applied to whichever colours you have most of in your wardrobe and pick the tutu in that colour. If you like green get green :)
