Le Freak, C'est Chic! A Roundup of NYC's Halloween Bashes

A 'too cool for school' crowd danced to the hipster music sensation Clap Your Hands Say Yeah at the Gramercy Park Hotel for the Vmagazine.com party, which was hosted by Nur Khan and Gemma Ward. Fashion royalty Julia Restoin Roitfeld-- looking beautiful even with fangs-- partied with boyfriend Magnus Berger, friends Genevieve Jones and new ‘it gal about town' Pamela Love, who was hoping to "catch a glimpse of Josh Hartnett even for two seconds." Across the room Lauren Davis, dressed as the Bride of Frankenstein (in vintage Christian Doir, bien sur!), held court with Derek Blasberg, and leader of the art kid-eratti Carlo von Zeitsel. Other guests included Chloë Sevigny, Lisa Cant, Mandie Erickson, Fabiola Beracasa, and Yeshwant Holkar who, as Hunter S. Thompson, was donning “the clever man’s costume” remarked Lauren Goodman.

Meanwhile uptown at the Roberto Cavalli and Cavalli Vodka Halloween Party at Cipriani, a ninja mingled with Snow White as half-naked men and women danced with cowboys, spacemen and pirates.

A select crowd – including Petra Nemcova (a.k.a. Cleopatra), Sarah Ferguson, Sean "Diddy" Combs, Marcus Schenkenberg, and John Legend – enjoyed a private dinner reminiscent of a medieval feast, where wine was flowing out of giant goblets. But the party really kicked off when Roberto Cavalli, surrounded by models in silver catsuits, danced on sofas to a musical performance by Eve. Of the evening, member Sabine Roemer said, "Great costumes, great drinks, fun people!" Other party- goers included Celine Assimom, Thierry Chaunu, Kristen Knapp, Rachel Chan, Neal Gorevic, and Oliver Jacquez

Late-night, the scenesters migrated to The Box for the Sagatiba Cashaca party. The notoriously hip club, famous for outrageous burlesque shows, put on a spectacle with scantily-clad dancing women and a mini-Michael Jackson who performed 'Thriller' with a dancing zombie. Arden Wohl, Leelee Sobiesksi, Ashley Olsen, Andre Balazs, Lance Armstrong and Alexander McQueen enjoyed the show and sipped deadly blood orange Sagatiba Cachaca cocktails.
