On Saturday night, Allison Sarofim hosted her annual Halloween party at her West Village house, and the strict theme was Japanese anime. So how did social ubiquity Sarofim come up with such an inspired idea? You know, the same as anyone might: "I was at a dinner in Moscow for Larry Gagosian, and I was seated next to [Takashi] Murakami, and I thought, 'Oh, anime.'" If you were lucky enough to snag an invite, you'd have seen Allison herself as Japanese weapon-toting superhero DNA, Sony honcho Rob Wiesenthal covered in lights as comic book character Lightning, Cynthia Rowley as a Harajuku girl, and Chris Benz in six-inch pink platforms and a matching catsuit. (Other guests included Padma Lakshmi (left), Ann Dexter-Jones, and Jennifer Creel.) Hey, no one said that being on the A-list wouldn't involve some emotionally-scarring experiences.
