Kate teamed the elegant outerwear with a matching tilted hat that featured a bow detail, navy suede pumps, a matching clutch, and her favorite pair of sapphire-and-diamond drop earrings and necklace. To top off her outfit, she traded in her signature wavy locks for a chic low chignon that complemented the rest of her ensemble.
