Otome wa Boku ni Koishiteru is about a boy who goes to an all girls school... Dressed as a girl of course.
These girls have a white uniform and a black one. The white one is quite lovely being a long dress. It has big cuffs which have a cute little blue trim on them to match the in your face big floppy blue bow they have. The bow has a cute little golden pin in the middle as well. It's a simple dress uniform but a really nice one. The black one makes me laugh because everything about it is all about the breasts. There is a white shirt opening right where the goods are to promptly display them under a huge red bow with the same pretty golden pin in the middle as the white one.
Overall: I'd go with the white uniform since I don't really have huge breasts to show off like the black one would.
