Francisco Costa's party to celebrate theCalvin Klein men's and women's Fall 2010 collections was staged in ahuge industrial, raw loft on Little West 12th Street. The interior feltlike Calvin's fantasy 1970s Aspen abode -- all-white leather couches,long, sleek fireplaces flickering rows of flames and model-boys pouringflutes of champagne. Everyone who survived fashion week came out totoast Costa, including: Kerry Washington, Alexander Skarsgard, NaomiWatts, Ryan Phillippe, Kate Bosworth, Brooklyn Decker, HelenaChristensen, AnnaLynne McCord and Kellan Lutz, and RachelZoe. The crowd also included Dani Stahl, Richard Buckley, Isabel Lucas, Hamish Bowles, Linda Fargo (dancing by the window), Stella Tennant, and fashion writer Vanessa Lawrence (it was her birthday). But the one boldface beauty that kept me entranced was former,notoriously outrageous 43-year-old supermodel Kristen McMenamy, who didnot disappoint with a frizzy mess of flowing platinum blond hair, lacestockings and white leather boots. McMenamy has sporadically appearedin Paris and Italian Vogue, but mostly is now a mom to daughter Lilywho she had in 1994 with photographer Miles Aldridge. She is no longera party girl and has a scant seven photos on Patrick McMullan's website. Iasked the androgynous stunner what she's been up to lately. "I'm justliving my life, man," she said, swigging her champagne. Cheers, Kristen.
