Celebrities have caught on to cobalt! Demi Moore wore the blue hue when she attended the Costume Designers Guild Awards in a strapless Vivienne Westwood gown last month, while Olivia Munn stepped out this weekend in an electric blue Marchesa dress belted with a matching sash. Abbie Cornish showed up to last week's Sucker Punch premiere in a cobalt Amanda Wakeley frock, and Dita Von Teese stopped by Perez Hilton's birthday bash on Saturday in a sequined Jenny Packham number.
