I've only been clubbing once, several years back, and I would say not everyone is dressed to the nines, some people dress pretty normal, like in jeans and T shirts. There are all sorts of people I guess, but oh, I would say its uncommon to see people wearing glasses in such places, but other than that, the dressing of people is a broad spectrum. But then again, for all I know, I don't even know what I'm talking about because I've only been there once..
