These shoes are very similar to the Opening Ceremony x Chloe Sevigny ones from last year but at a fraction of the price. I found these on super sale here at Piperlime.com for $29.99. They are excellent quality for the price you get them for and are pretty comfortable for a shoe this height. The only think they lack (compared to the Chloe Sevigny version) is a detachable bow.. but I think I can sacrifice the bow for saving hundreds of dollars.
