Parties! The style, stars and scoop from Hollywood's hottest events

Molly Sims (in Bensoni) debuted a darker 'do at the opening of the West Hollywood outpost of design emporium Moss. "There are a lot of avant-garde, forward art people in here," said the bi-coastal Las Vegas star. "It's very New York!" The eclectic objets for sale—including laser-cut wooden furniture and a Swarovski Crystal Palace installation—also served as the evening's decor, while Dutch designer Maarten Baas provided the entertainment, tickling the ivories on a fire-sculpted 1938 Steinway Baby Grand piano.
