The Tribeca Film Festival began with a bang last night with its star-studded Vanity Fair kick-off gala. Countless familiar New York City names were spotted at the annual event, from the festival’s founder Robert De Niro to “socialite” and headband-wearer Arden Wohl. This is New York City, after all, so naturally many of the partygoers were in head-to-toe black looks. Adorably preggers Evan Rachel Wood was radiant in a flattering black halter dress, and Sienna Miller looked rad in a short black-on-black floral frock that showcased her killer shoes. Both Karolina Kurkova and Rachel Roy chose pantsuit looks for the occasion, and Whoopi Goldberg looked like the awesomest good witch/cool aunt ever in her trademark Cool Flowy Black Thing. (I love Whoopi.) So! Who do you think wore black better at the Vanity Fair party? It’s a tough call, right?
