I'm with Pupik and Neon. My musical tastes are so varied if I had to emulate the styles I'd need another house just for clothes.
I used to try and project some image that told everyone what music I liked, back when I thought I was cool. And I'd have to say that elements of the styles have been permanently integrated into my "look." But I've always prefered to look pretty generic. I don't want to be labeled on sight.
One interesting way to observe the phenomenon is by going to shows. When I was way younger and going to big giant concerts in big gaint concert arenas named after big giant corporations there was definitely a homogenous look to most everyone there. And of course they even sell that look.
But since I've started listening to more independednt, non-popular music, and going to their shows in cozy bars and small venues, the phenomenon of imitation is mostly gone. The last show I went to, The Sea and Cake at Nita's Hidaway in Tempe, AZ, had an audience of about 200 spanning ages from about 17 to, well, probably 40 or so. All the youger people were dressed the same. All the girls had horned rim glasses. All the guys looked like mod nerds from the early sixties wearing Dickies and stripes (like that record store guy on that American Dreams show). My wife and I looked like we always do, casual and comfortable. And the rest of the adults did, too. And the funny thing is that the band looked nothing like their fans. One was just some dorky guy with jeans and an oxford shirt (synths, hand held percussion, organs, trumpet); one was an American Indian, long hair (elec. bass). One was wearing jeans and a sweater which he took off to reveal a plain t-shirt (elec guitar). One was wearing black jeans and a denim jacket (elec. guitar). And the drummer was wearing jeans and a t-shirt, his arms from cuff to shoulder covered with tatoos (duh). A truly mismatched group if you're looking for a coherent image. But then they're all around thirty.
I think it's an age thing. Younger people are searching for an image, and during that search they're prone to change dramatically and quickly, basically being followers. As one matures over time, elements of that process fall away and others stick. And Voila... a carefully crafted, time tested image
