A-listers ventured through the snow in New York on Wednesday to fete the American Foundation for AIDS Research (amfAR) at the organization's annual benefit and celebration of Fashion Week's kickoff.
The guest list was packed with some newly single girls (Heidi Klum) and some newly expecting (Molly Sims, Julia Restoin-Roitfeld); some fashion royalty (Cindy Crawford, Sarah Jessica Parker, Liz Hurley) and some newcomers (Leighton Meester, Jessica White).
And there was at least one surprise guest: Lindsay Lohan, who appeared in a tight white dress and messy blonde hair.
SJP wore her pre-fall 2012 Oscar de la Renta pink gown under a leather biker jacket. Others like Cindy Crawford and Leighton opted for standard issue plunging necklines.
One of our favorites was Jessica White, who paired her bright orange frock with a whimsical gold headpiece.
