Parties! The style, stars and scoop from Hollywood's hottest events

Though starlets like Anne Hathaway are often seen in the fun, flirty designs by Keren Craig and Georgina Chapman, it was Renee Zellweger who put the duo—and their label, Marchesa—on the map. "Renee wore Marchesa to a premiere," Chapman has recalled. "The next day she was on the cover of every newspaper. We nearly died." So why is Anne—who wore the label to the 2008 Oscars—such a fan? "A fitting with them is like a party!" Hathaway has declared.
