If you haven't been to The Sartorialist you need to check it out. It's a great blog if you are into fashion or just people watching. I had to read post this lovely lady and what he had to say about uniforms.
"Uniforms are, by nature, an attempt to make people conform to a code. I always find it interesting when people are able to play within the set boundaries of a code while still not totally losing their own uniqueness."
