Who's using Anna Wintour's name to sell leggings on Twitter?

Anna Wintour, Vogue's imperious editor-in-chief, may or may not be a fan of designer leggings, but she doesn't love them enough to tweet about them -- or about anything else, for that matter.

Earlier this year, an anonymous Twitter user borrowed Wintour's name to create an account, RealAnnaWintour. The account, which has racked up 760 followers and counting, appears to have been started to promote a year-old clothing company, David Lerner Collection, which produces leggings, T-shirts, and other garments.
