I'm a 20-something graduate student who found Polyvore through Pinterest. It's a hobby of mine that I enjoy doing and it helps me relax from life's stresses.
My style philosophy is less is more. I rarely use jewelry or other accessories beyond outfit staples in my sets--Sometimes I experiment with photos and such, but I believe that the focus should be on the outfit, which should serve as inspiration for you. As Tim Gunn says, it's up to you to "Make it Work!"
