I've been blogging on Fairy Shoe Princess about shoes from The City and I think I found both of Whitney's black pairs. You can see them at BCBGMAXAZRIA, but they are sold in a few other places. It's the Monroe (ankle strap) and the Gianni (cage heel). I've looked everywhere for these and they are definitely the closest I've found, if not the exact shoes.
