How brilliant of Marc Jacobs (and his twenty assistants) to address the expanding needs of the modern woman! His latest, the Sienna Hobo, is the ultimate bag. Sleek and chic when zipped, it also unzips into a roomy and slouchy carryall when needed! In rich burgundy leather lined in brown suede with gold hardware, the Sienna is a must have in The Bag Snob’s collection. $925 at eLuxury.
