The grunge look was welcome, but, imho, but it's like a pendulum swinging back and forth. Just like we needed something to counterbalance the excess of leather and spikes and glitter and hair spray I feel that the opposite excess (which is just as calculated) is getting old.
I don't think it depends on the music you like, not strictly. I love all kinds of music. I was a DJ back in the early-mid 90s and I have very fond memories of the grunge scene exploding - bands like Nirvana, Soundgarden - and even Pearl Jam (

there, I said it). It was great to see people on stage that weren't all made up and apparently were there for the music.
But THAT became just as fashionable. Anyone wearing a tuque on stage is as big a poseur as any of the guys in Poison, anyway.
I don't think I'm being partial to music I like. I mean this below is one of my favorite bands. As much as they influenced me musically, I don't think there's any piece of clothe I've ever owned which was a result of me trying to emulate their sense of fashion. That's as bad as hipsters. Heck, I wouldn't want to be in the same room as them or even touch them with a 10 ft pole.
