What are the teen trends for summer 2011?

i'm 13 in 7th grade...and i usually like to set the trends in my school. i know that during this winter there were the Osiris' and monster hats and dc hats....i was wondering if they're still going to be in for spring and summer. And since it's spring break i thought i could come back with some brand new sneakers or something. does anybody know what i can do?
