How to dress in highschool? + Organization?

I'm going to be a freshman also, and just because you wear those clothes, doesn't make you trashy. I'm going vintage, the previous year, I wore alot of Hollister, as you might see as my questions I have asked, I'm confused also, but forever 21 has alot of cute clothes! Cato is also a good place, pacsun, is also good. And for school, I would just a big binder with dividers, one for each class, but that's just me. :)
