Julia, I just bought this bag at NY & Co:

Yeah, it's pretty plain, but it will do the job for school, I think and be more stylish than my current backpack. At $33.00 I don't have to worry about it getting totally ruined either. I know the one I bought is too big for your needs, but most of their bags seemed to come in white, so I thought you might at least check them out. Most of them are under $50.00.
