Over the years, Nicole Richie has experimented with different hair colors and lengths (who can forget those ultralong extensions?). She even started a stylish surge of wispy blond bobs. At an event in Los Angeles last night, Nicole showed off a different look, wearing beachy-cool, chest-length waves — a sure sign that she may be letting her golden locks grow out for the new season. (Or perhaps an indication she's gotten some strategically placed extensions.) What do you think of her longer style?
