She wore the same green uniform as all the other young cleaning ladies but, as you can imagine, she was the only one that really stood out in that crowd.

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.
