I really liked the uniform and the muggle clothes. Harry Potter's supposed to be set around now, just because it was written in 1999 doesn't mean the movie has to be set then. I think Hermione's clothes were a little too fashionable, though. She was wearing the kind of thing someone like me would go out and buy, not the kind of thing that Hermione would wear.

And I loved the Quidditch uniforms!

Plus, Hermione and Harry come from Muggle families, so of course they'd be wearing normal stuff. In GoF, the Weasley children are described as wearing normal Muggle clothes, so I think it's just right.
