Reese Witherspoon has seldom been spotted out on the town since the birth of her son, Tennessee, ten weeks ago. But last night she glammed-up with the help of her favourite designer Elie Saab to support the Children’s Defence Fund in California. She paired the LBD with black Christian Louboutin stilettos and straight, side-swept hair. Saab is a Lebanese couturier and ready-to-wear designer who works from his studio in Beirut and shows at Paris Fashion Week.
