Some of the more disco-like beats seem dated, but that is about it. Tight skin female uniforms is sort of a sci-fi staple in Japan. They are lucky they aren't showing off a lot of skin. Though it might be nice for them to be in the regular uniforms, I suppose it was (A: tradition) and (B: unflatering for their figures).
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.
