Nothing sexes up a tee-shirt-and-jeans day like a sexy, loose chignon. Sure, Jennifer Hudson wore this ‘do to the Kennedy Center Honors (a decidedly fancy event), but the style looks just as chic — if not more so — with a casual outfit. The great news? This chignon is a lot easier than it looks. To do, part hair slightly off center, and then use fingers to loosely twist the front sections backwards. Gather the two twists and the rest of your hair in a low bun, and then spritz allover with a a light hold spray like Mizani Shimmer Reflects Spritz, $14, amazon.com.
