"I feel like the girls are my peers, my generation. We're always hanging out, bouncing ideas around," said Kate Bosworth to explain why she'd flown in to introduce her Pasadena friends Kate and Laura Mulleavy to London last night. The British branch of the Rodarte appreciation society—Emma Watson, Daphne Guinness, Caroline Sieber, Plum Sykes, and Bella Freud, along with U.S. girlfriend-supporters Liz Goldwyn, Trish Goff, and Elizabeth Saltzman Walker—convened in department store Harvey Nichols, where the fifth-floor restaurant had been unrecognizably magicked into an all-white mise-en-scène. Laura Mulleavy said she'd dreamed up the scheme long-distance. "I was thinking Yoko Ono and John Lennon, and Joy Division for the place names," she said, looking at guests seated at a long table decorated with dozens of vases of white sweet peas.

Conversation swirled around the delight of wearing a Rodarte dress. "Deconstructed ballerina," chirped Bosworth, doing a slow twirl to demonstrate the slashed leather spine-and-ribcage formation of her bodice. The sisters' laid-back niceness, miraculously undented by the grueling 14-hour LAX-Heathrow flight and the prospect of a 48-hour turnaround, was another point of admiration around the room. Why the swift stopover? "Well, we've got to get back home and then be in New York for the CFDA Awards," shrugged Laura. "We're up for Womenswear Designer. It's us, Marc, and Narciso, so that's really big for us."
