Whoever deejayed the Halston post-show bash at Don Hill's treated partygoers to a decibel level usually reserved for ambulance sirens. We were eager to find out how designer Marco Zanini felt about his debut, but the doo-wop beats of "He's So Fine" drowned out any attempt at communication. Then one of Zanini's backers made herself heard above the din. "Marco was able to keep the Halston DNA and bring it back in a really modern way," said Tamara Mellon. Meanwhile, her actor beau, Christian Slater, surveyed the indestructible downtown nightclub. "I don't remember ever being here," the reformed bad boy said with his crooked grin. "But that doesn't mean I never came."

Joie de Vivre
In a bid to give the Joie aesthetic a shot of youth serum, the label recruited a quartet of PYTs— Julia Restoin-Roitfeld; her brother, Vladimir; his girlfriend, Lily Donaldson; and all of the above's mutual pal Theodora Richards—to host a little fashion week shindig at the Gramercy Park Hotel. Spotted in the thicket of models and cigarette smoke were Olivier Zahm, Duran Duran's Nick Rhodes, Craig McDean, Anouck Lepère, Victoria Traina, and, of course, the Roitfeld kids' Givenchy-clad mom, Carine.

Double Date
Officially, Chloë Sevigny's bash at Webster Hall was in celebration of the actress' new line for Opening Ceremony. Unofficially, it was the Proenza Schouler after-show party. "I don't blame them for tagging on to Chloë's party," said Vanity Fair's Elizabeth Saltzman Walker of Jack McCollough and Lazaro Hernandez. "She's supercool, and their ideal customer." So supercool, in fact, that with a little help from seminal all-girl punk band the Slits, she made this pre-millennium concert hall seem almost hip again.
