A cute bag is a girl's best friend. And, like girlfriends, you need more than one: Each bag in your collection should fulfill a specific need, appeal to a certain facet of your ever-changing, sparkling personality. The Pink Purse celebrates such diversity with a selection of hip pocketbooks that range from functional to outright silly. Hooray for the Zippurse and the Original Seatbeltbag for turning everyday materials into something fabulous and durable; three cheers for Matt & Nat's PETA-approved synthetic leather "vegan" bags in fun colors; and kudos to Little Earth's molded license-plate bags, including a Euro-sleek Italian one and a rootin'-tootin' Wyoming model with a root beer bottle-cap clasp. Thank heaven for Hello Kitty couture, suede-fringed hobos, corduroy clutches and everything in between. Hey, it's in the bag.
