Carly, best idea for a school project EVER!!!!! My only suggestion is to address both sides. Maybe try interviewing some people that know their bag is fake and are (gasp) proud of it, find out their reasons why they bought it, where they got it (dangerous conditions maybe?), will they keep buying (implications on what the supports outside of just cheaper "fashion"), and if any of them know what "buying knock-offs" does to the economy and society at large.
