On an L.A. weekend with an event around every corner, Diane von Furstenberg stole the spotlight with Friday's opening celebration of her new exhibit, Journey of a Dress. Guests like Uma Thurman, Tobey Maguire, and Demi Moore mingled among the 200 dresses in nearly 20,000 square feet of exhibition space. "Everyone knows why they're here," said Coco Rocha, who, alongside Andy Cohen, was providing live red-carpet coverage. "Everyone has a story about their first wrap dress."
Along with the legion of mannequins donning decades of the designer's iconic dresses, Von Furstenberg's likeness was everywhere you looked, from those famous Warhols to playful illustrations by Antonio Lopez, Ruben Toledo, and Konstantin Kakanias. A Ghost May Come, a new work by Dustin Yellin that features the body of a wrap dress suspended in glass, greeted partygoers upon entering. After posing for photos, Von Furstenberg made her way to the back room, reimagined in the disco decor of Studio 54. "Diane pioneered this movement," said Robin Wright, who was wearing a wrap dress of her own. "She made the most practical, pragmatic, sexy dress for every woman, no matter what their shape or size. No wonder she's going 40 years strong!"
On Saturday, it was Sean Penn's third annual Help Haiti Home event, in partnership with Giorgio Armani and benefitting Penn's earthquake relief charity J/P HRO, which drew Hollywood's big names—Julia Roberts, Gwyneth Paltrow, Chris Hemsworth, and Idris Elba included. "The glorious and resilient Haiti is the country we are blessed to have as our neighbor," Penn told the crowd. "Help us finish the job."
After his impassioned speech, the live auction heated up. Chris Martin bid against Charlize Theron for a brand-new Banksy, made by the artist specially for the event, while Piers Morgan and Anderson Cooper vied for a commissioned work by Jeff Koons, featuring Penn's collection of decommissioned guns. Cooper eventually won. At the end of the night, U2 took to the stage for a surprise set. Bono kicked it off: "It's been a while since U2 played a hotel lounge."
