Ohmuhgoodness. The 'Juva' pumps from Gwen Stefanie's line L.A.M.B. are to-die. These four-inch heels mix a black-and-white houndstooth pattern with optical illusion-like boxes. These would look great with skinnies or black tights and a skirt when it gets chilly.
I love the square toe and 3/4" platform. Plus, in black and white, they'll go with a lot. They're priced at $353 on Zappos.com.
