Ah, very sorry, should have pointed you to some of the interesting fashion I was referring to.

Obon Pictures - In Okinawa you are bound to see many Japanese dressed in traditional okinawa uniforms or other types of cutesy outfits.

Okinawan pictures - In Shinjuku, there is an entirely different type of fashion, that is more modern/hip/cool. If Akihaba has the nerds, this district has the "cool kids"

 Those are the two major districts that I know of, where Japanese fashion (beyond the normal jeans and a t-shit) really stand out. Hope that helps.
