What do Fabiola Beracasa, Claire Bernard, Amanda Hearst, Tinsley Mortimer, Leelee Sobieski, and Arden Wohl all have in common? Besides the obvious? Well they are, of course, the "Dance Chairmen" of "The Annual Winter Dance" at the Natural History Museum. $7,000 is a small price to pay to guarantee you have a table next to the fabulous "queen of head wares", the "Supergirl", and the "savvy belt-wearer". If that doesn't interest you, just remember, it's for a good cause, Roberto Cavalli is hosting, oh and....it's tax deductible.
