Where Can I Find Unique Clothes?

I'm sort of tired of wearing the same clothes as most people, so I'm looking for websites that carry unique but nice clothes. They can be casual, slightly dressy, whatever. I don't want anything slutty, but showing a little skin is fine. I just want something different. I would also prefer websites that won't totally empty my wallet, since I don't have very much money. I like websites like ModCloth and Nasty Gal. I am 20, so I'm not going for anything incredibly refined. If you could give me a good number of suggestions, that would be great! Thanks!
