Dressing for your taste in music

I think that its something mainly teens do, you know having to dress "edgy" and in lots of black etc if you like emo music like I did but why is that and why some people never stop with it? Me i've grown tired of so much dark clothing, I like bright colors now and cute stuff which I kinda always have just like bright makeup colors suit my face a lot more than dark tones but when I was younger I had this really strong compulsion to dress like the music i'm into and fit the right aesthetic which is stupid. I've stopped wearing tons of black eyeliner now and I feel very bored and disappointed with myself that my wardrobe is so boring and lacking color. I still listen to rock although I kinda prefer interesting, psychedelic melodic songs nowadays and when it comes to rock I prefer grunge and post-grunge over emo or screamo which I dont even like anymore. I guess it really was a phase after all.
