Louis Vuitton, Isaac Mizrahi, Givenchy and other designers all showed backpacks on their runways this year. The look has spilled into all prices and more affordable designers have jumped on the bandwagon; these bags are just now coming into stores. Rebecca Minkoff, Kooba, Foley and Corinna, MZ Wallace all had them in their holiday/resort & spring 2011 collections, just to name a few. Have you seen one you love yet?
