The official arrival of spring means there's no better time to add to our sunglass collection. This year we're obsessed with STATE Optical Co.'s line of groovy-luxe glasses. There are many great styles for both guys and gals - all made here in the U.S. - but, our favorite is the Burnham sunglasses in tortoise sage. The sharp delineation evokes a multidimensional shape, evocative of the work of Chicago-based architect, Daniel Burnham, after whom they are named. Get your pair online at stateopticalco.com. $363.
