At a recent state dinner for the Mexican President and his wife, Michelle Obama was a vision in iris blue -- a gorgeous, one-shouldered, chiffon gown designed by Peter Sorenon. The gown featured layers of luscious chiffon and a touch of shimmer, and was worn belted in silver. Elegant, on-trend, and so perfect for the First Lady -- already acknowledged as this generation's First Lady of Fashion. Want to capture that shade this spring? Try it in a bag, a pair strappy of sandals, or on your toes. OPI Nail Lacquer in Give Me the Moon! is a romantic, silvery blue-violet.
