Princess Grace's granddaughter Charlotte looked cool in a black off the shoulder top at the Longines Global Champions Tour Grand Prix de Paris. She completed her outfit with a pair of round sunglasses and wore her brunette tresses in an updo along with a dash of red lipstick for a glam finishing touch.
