Week in Red Carpet 4/9

Though she’s now better known for her Twitpics than her red carpet glamour shots, actress Demi Moore returned to the red carpet Thursday night at the Los Angeles premiere of her film The Joneses. Moore turned heads in a magenta suede Marchesa masterpiece from the designer’s Fall 2010 collection. Adorned with paisley appliqués and a playful bustle, the cocktail dress was complete with a multi-colored Roger Vivier clutch, Van Cleef & Arpels jewels, and silver Brian Atwood pumps.
