What are the popular trends for teenagers, right now (other than emo)?

I remember when I was in highschool, the hawaiian theme was very popular.

As a member of this generation, I guess I could Try to fill you in. Other than emo, (which has by now become almost nonexistent), there is the new rave revival, the new hippy revival, classic rock revival, basically a lot of retro trends. That is to say that it has just begun to enter the mainstream. If you were to ask kids what their favorite music to listen to is, a growing percentage would list off 60s, 70s, and 80s bands, along with some new stuff from the current decade. With the new hippy revival, you basically have the return of the ripped jeans, peace signs, psychedelic or retro bands' shirts, etc. I've even seen a few kids wearing the glasses John Lennon used to wear at my school. A lot of people wear band t-shirts like Pink Floyd, Led Zeppelin, and The Beatles. And there's a lot of underground bands that people are just now getting into around now that try to replicate the sounds of the 60s, and 70s. Bands like The Society of Rockets, Black Mountain, The Blue Van, The Coral, Sky Picnic, Amplified Heat, and Wolfmother all have the same sort of "sound" that past rock groups used to play back in the day. I'm not trying to say that this is my Entire generation, but it's fastly growing percentage. It's grown especially this year. Unfortunately, Hip Hop still has a death grip on the current music industry and fashion, but if you were to look around, even that is sort of crawling back into the underground, it's not as mainstream as it used to be. Anyway, that's what I've been seeing in my school and hometown, peace!
