Terrible news for sun-worshippers and tanning salon habitués: Mahogany-hued skin is officially a fashion no-no, so drop that bottle of sunless tanner, pull the blinds down, and be grateful we've brought this breaking news to your attention. Make-up artist Charlotte Tilbury—who confesses to being partially culpable for the bronzed craze after she gave Kate Moss a dark tan for a 2002 Vogue shoot, a look that was replicated in the model's campaigns for Roberto Cavalli (himself a walking cheese doodle) and Louis Vuitton—is deadly serious when she warns: "The backlash is going to be huge." Not convinced? Listen to Simon Doonan, whose word on such matters is not to be trifled with: "What once looked healthy and lush now looks cheesy and has baaad connotations... I associate a tanned look with skin cancer." Say no more, we're canceling our Christmas trip to St. Barts as we type.
