Women’s Wear Daily celebrated their 100th birthday at a fashion-packed Anniversary Gala in NYC on Tuesday night, which attracted everyone from the Devil herself Anna Wintour to Tsunami-surviving supermodel Petra Nemcova, who dominated the red carpet in a cobalt blue Notte by Marchesa frock with ruffled sleeve detail. The Sports Illustrated covergirl paired the color-popping dress with black tights and heels for a sexy and sophisticated look.

Also dressed in Gossip-worthy getup at the swanky style party was the gorgeous Jessica Szohr, who wore a tuxedo-style jumpsuit from Juicy Couture by Erin Fetherston with leopard print Christian Louboutin booties, and the Olsen Twins (although PETA probably wasn’t too happy with their fur-bulous coats).

Margaret Cho had us laughing with her truly awful attire, though her mismatched a la mode seemed a tad contrived. Susan Sarandon hit the NYC premiere of 127 hours dressed in granny getup, while David Arquette was up to his usual attire antics in Hollywood.

Other notable nods? Julianne Moore dazzled at the Rome Film Festival premiere of The Kids Are All Right wearing a blue satin Giorgio Armani Spring 2011 one-shoulder gown with Bvlgari accessories and Renee Zellweger who enjoyed dinner with Bradley Cooper’s folks in fab fashion.
