Clubs/bars in shockoe used to (I haven't been in years but I'm sure it's the same) post signs about "dress code" with things like "no fitted hats, no cheetah print leggings, no baggy jeans, no gold chains, no air Jordans" which was very clearly targeting a specific demographic. Then you'd go in and there'd be white guys walking around in flip flops, ball caps, and dingy tee shirts. The dress code in those places has always been about keeping certain kinds of people out, not about appearances.
