i dont know why people make such a big deal about "button down shirts" vs "t-shirts" - i think if you want to look good - you can...no matter what you're wearing...and that should have nothing to do w/ how the music sounds... As human beings in general, we have always lived in judgemental societies (which is sad but true) and people in public places always judge you by the way you look... arent some of us already concluding that people wearing button down shirts arent "real clubbers" and are there just to pick up girls and dont know anything about the music? - thats generalizing right there... i like the way the crobar crowd looks...i dont think you need to wear button down shirts to get into places like crobar or any other place w/o a dress-code for that matter - i think (no matter what you're wearing) - if you look presentable and "look good" - you shouldnt have any problems getting in... i like girls who dress up and i also like girls in t-shirts and jeans - wearing those funky club outfits - being creative...and altho i go to all these big clubs for the DJ, i'm not gonna lie when i say that having a bunch of hot women around you is always a plus - i mean d-uh - i am a guy after all
