How it works: This buzzy site, which raised $5M from Google Ventures last year, features cast-offs from bloggers and stylists like Brad Goreski. There’s also a social discovery angle. To list, you just pay a 3.5% transaction fee. You can sell just about anything that falls under the clothing/accessories/jewelry categories.
Pros: It’s not too selective, and is easy to use.
Cons: Could be a bit overwhelming to shop–the whole social thing isn’t for everyone.
