Ghetto Uniform
Generally a white T shirt (sometimes very long) and blue or dark jeans. Worn by youth in urban areas to make themselves look the same (uniform).
Miss can you tell me what he looked like?

I don't know, it happened so fast. He had on blue jeans and a white t shirt.

Uh, miss...there's about 100 guys out there wearing that, it's the ghetto uniform.
