Help me be a(n) Indie/Hipster?

I am one of those people that love to listen to good music (sometimes bands that people have never heard of), doodle all the time, ride my fixie (fixed gear) etc. My friends say I am an Indie kid, but that I don't dress like one. How does an Indie kid dress? My friends also call me a Hipster, but I dont know what that is.
