Chanel Iman, Diane Kruger, Alessandra Ambrosio, Camilla Belle, Kate Bosworth (Getty)This round was all about sophisticated elegance. First, it was Chanel Iman who set the tone in her sleek black gown at the Ralph Lauren screening. Kate Bosworth followed suit in her Christopher Kane dress at the Big Sur premiere, but went for a side of embellishments.
Diane Kruger and Camilla Belle were in the same mood for their fancy fetes—Diana hit up Brazil in Chanel's beaded floral LBD while Camilla was a total gem in Oscar de la Renta's blue embroidered frock. It was Alessandra Ambrosio, however, who won the chic competition of the week, just barely beating out Rosie Huntington-Whiteley with her champaign blouse and cigarette pants. But will she triumph in this showdown? You tell us.
