I think the major problem I have with the female uniforms is that there's a part that could be removed and show off the girls' cleavage. I'd been fine if they gave the girls the regular uniform shirts over the tight pants in the current uniform and make the shirts hug their curves a bit more.
They could, but in the original series they never did that with Yuki. (they did other things, but never cleavage via her uniform)
Plus with the male unforms it would probably be as easy (or easier) to undo the top and show off. If I remember correctly, the original version had Kodai with his shirt open or off several times during the course of the series. Having the shirt open back then was interesting...since it usually was drawn as a pull over.
