Polyvore is a ever-growing user-generated data base of fashion items, including accessories and furniture, that you can upload, mix and match. The interface allows you to re-size items and layer them, creating your own unique ‘looks’ that you can save as sets. The items are poached from other sites, but each one is carefully labeled, and the source identified (just in case you want to recreate your wardrobe ideas IRL).
I am interested in how they plan to make money. Affiliation is an obvious route, but not so obvious in practice, since the users are finding and creating the images. A partnership would make sense, where a 3rd party would supply pre-masked images and links and populate the database with their latest fashions, and pay Polyvore for the privilege of exposing their wares to fashion mavens.
It makes perfect sense that Polyvore also has a Facebook application.
