Polyvore is a social media site with a twist. It's completely fashion/art centered where users create 'sets' or 'collections' with photos and items. These items are imported automatically from almost all online stores, and if the items you want to use aren't already there, you can import them on your own, easily. I've been a member for over 7 years, so I have been along for the ride. Polyvore launched in February 2007 and though many changes, making everything more community based, more streamlined, more user friendly; the basic premise has always been the same- create and share.
Now, Polyvore boasts cool features including the ability to add music to your sets, text generators, and even contests.
I have loved this website for a long time and love to spread the word.
The simple drag and drop interface is both easy to use and very gratifying. You can find my Polyvore profile here, and Allison's here.
I highly recommend this site to anyone interested in art, fashion, home decor, or creative expression.
