Kate Middleton Makes Royal Decree: Leggings Are Pants

Yep, the Duchess of Cambridge rocked them while shopping at her local Lululemon. (She probably was in there to stock up on a fresh supply of stretch, obviously.) Her royal trick to keeping the look sleek, not sloppy: by pairing it with a structured purse, jacket and her signature bouncy blowout. The lesson? You can wear leggings as pants--as long as you wash your hair. Done.
