Style setters Ashley Madekwe, Jessica Alba , and Nicole Richie  all turned up to celebrate Who What Wear's 50 Most Fashionable Women of 2013 event last night — navy, black, and white have never looked so good. Ashley and Jessica each opted for cute short looks, with Ashley wearing a subtly striped navy ensemble, accessorized with a pair of red sandals and a classic box clutch, while Jessica debuted a white, long-sleeved dress by Wes Gordon. Jessica finished the look with a rectangular black box clutch and a pair of metallic cap-toe heels. Nicole channeled Catwoman in her low-cut sequined dress, which she wore over leather leggings, complete with a lacy, cat-ear headpiece, and finished things off with a nude clutch.
