How it works: Poshmark is a bit Pinterest-y. You simply create a “closet” (of women’s clothes and accessories), which people can shop from and you can follow people whose style you’re into. There’s even an Instagram-like app you can use to photograph and list your unwanted goods. They provide shipping labels and you keep 80% of the selling price.
Pros: Simple platform, functions well on iOs.
Cons: Seems like the kind of site you might end up spending a long time on without actually buying anything.
