the female uniforms at ludwidge in pandora hearts are actually quite cute... it's the first one that came to mind, but otherwise i don't really care for uniforms.

reading over the comments as well and i do agree that the student council uniforms in shinshi doumei cross are really nice--! i don't run into very many series where it's not against the school rules to alter your school uniform, so it's a very nice change. :>
