Where can I get fashionable clothing for a teenage girl?

Hi, I am in high school and I am honestly sick of the name brand clothing like Abercrombie & Fitch, Hollister, Aeropostale and so on. I am hoping to change my wardrobe this summer to clothes that aren't filled with graphics and make me look stylish. I would love some new accessories as well, and I am looking for suggestions. Thanks so much :)
