If you were bewitched by the buckled and bejeweled stacked-heel mules, booties, and oxfords that the Proenza boys sent down the runway of their Fall 2010 collection, then boy, do we have news for you! The shoes, which never went into production, are exclusively being sold at OC online. These seriously vertiginous (yet surprisingly wearable) shoes come in either size 39 or 41, and only six pairs are available. If that's not one-of-a-kind, then we don't know what is. Phone order only.
