We remember when Paris Hilton was the height of dazzle-me glamour, and she toted little Tinkerbell around town in a Louis Vuitton carrier. It was then that dogs became more than just friends, sheep herders, or things that inconveniently pee. They transcended into accessories, turning up on red carpets, at restaurant tables, and on the Gaultier runway. And they spurned a ton of fashion-related products: "Chewey Vuitton" toys, Goyard collars and leashes, an entire wardrobe line from Burberry and Juicy Couture. But now Paris has tarnished, dogs have (mostly) returned to the man's-best-friend role, and there's a new space for accessory spawn: The super-deluxe cell phone. LV and Chloe have made iPhone cases, Henry Holland and Giles Deacon have designed Blackberry wallpapers meant for download, and Diane Von Furstenberg has splashed her signature lip print on Sidekicks (rumor has it Heatherette is next). There's even a new line of purses designed especially for Blackberries, and spinning out of London's Violet May boutique. They're absolutely gorgeous, especially for cocktail parties where you want a dainty clutch but can't bear to be without your phone. And yet, we have to ask: Does everything need an accessory?
