• Real estate prices are plummeting and deep-pocketed buyers are hard to come by, but that hasn't changed things at 820 Fifth, the notoriously picky co-op where 89-year-old socialite Jayne Wrightsman reigns supreme. Jeff Blau, the 41-year-old president of The Related Companies, had been willing to pay a whopping $31 million for developer Ara Hovnanian's fourth-floor apartment. But Blau and his wife Lisa were told to get lost even before they had a chance to interview (and despite an intervention by the mayor). At least they're in good company: Ron Perelman, casino mogul Steve Wynn, and oil heir Fred Koch are all past rejectees. [NYO]

• It wouldn't be fashion's biggest night without a bit of drama thrown in to spice things up. Naomi Campbell, Linda Evangelista, and Christy Turlington are reportedly skipping the Costume Institute gala this evening, possibly because Kate Moss was chosen to co-chair the event; meanwhile, Karl Lagerfeld, Azzedine Alaia, and Domenico Dolce and Stefano Gabbana are all staying home, perhaps because Marc Jacobs has "commandeered the event" by buying two tables and dressing Moss, Madonna, and Kerry Washington. [P6]
• The Chelsea Clinton wedding rumors continue: The Boston Globe reports the former first daughter and Marc Mezvinsky may get hitched at Ted Danson and Mary Steenburgen's home on Martha's Vineyard in August, which is when the Obamas will be in town, too. [BG, NYDN]
• Kelly Killoren Bensimon says picking on her has become "the new recession vocation." Sounds about right. [R&M]

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.

Just because the stock market is continuing to flail around, that doesn't mean people should forget this month's primary issue of national import: Who's going as what for Halloween? The Transom has helpfully surveyed the city's glitterati in order to discover what costumes we'll see at the Central Park Conservancy Halloween Ball, Allison Sarofim's party, and Susanne Bartsch's bash. While some people are as yet undecided—poor Fabiola Beracasa's been so rushed off her feet, she hasn't even had time to think, and Charlotte Ronson hasn't made up her mind either—others are all set.

The daughter of a billionaire financier, social fixture Allison Sarofim has dabbled in writing, restaurateuring, acting, and art collecting.

Avenue, the magazine of choice for the filthy rich, put Allison Sarofim on their new cover. The young(ish) socialite is sitting on an Eames chair in a Chanel dress. What looks to be a script lies open on the floor. "Downtown Doyenne," proclaims the headline: "Allison Sarofim takes the party south." Why do we never think about her? We have been missing out!
