Always eager to kiss up to celebs, the fashion industry invited these tiny titans to the CFDA Awards' 25th anniversary last year, where they rubbed insiders the wrong way by addressing the snotty crowd as their "fellow designers." Scissor wizard Phillip Lim even sniped that their prominence was "unfair." The waify divas—who control an estimated $1.4 billion empire—launched two clothing lines in 2007 alone, and, between them, have graced the covers of Nylon, Harper's Bazaar, Marie Claire, and Teen Vogue. But their greatest coup is the accolade they now share with Anna Wintour: the wrath of PETA, who dubbed them "Hairy-Kate and Trashley Trollsen." When people start throwing blood in your face, you know you've arrived.
