Say what you want about Lydia Hearst, but she takes her spokesmodel duties seriously. At last night's premiere of Australia at the Zeigfeld Theater, the socialite and erstwhile columnist wore a dress that was, she told the Daily Transom, inspired by the film. But what, exactly, does a floor-length purple halter with Japanese buttons up the side have to do with Baz Luhrmann's epic about an aristocrat and a cattle herder in pre-World War II Australia? "There were actually a lot of Asian seamstresses in Australia during the pre-WWII era," said Lydia. "And you don't see dresses like this anymore." Possibly a good thing, but you be the judge.
