The utility bag gets a fashion makeover with backpacks to suit all moods and occasions. Weekend in the city? Try a boyish Herschel backpack, canvas style Longchamp backpack or a playful Marc by Marc Jacobs backpack. For a smarter option, Maison Margiela and Ally Capellino's sleek leather styles hit the mark. The ultimate fashion backpack? It has to be an Alexander Wang creation in slouchy washed leather, one of the statement printed Givenchy backpacks or one of the skillfully crafted luxurious leather Mulberry backpacks.
