Kate Middleton is no stranger to Wimbledon. As patron of the All England Lawn Tennis and Croquet Club, she often attends alongside Prince William or members of her tennis-mad family. But when she made an appearance at the men's semi-final and women's final on Saturday, she had a new companion: her sister-in-law, Meghan Markle. The Duchess of Cambridge and the Duchess of Sussex put on a seriously stylish show as they settled down to watch the action. Kate stuck to her Wimbledon go-to, a pretty Summer dress, this time opting for a slim-fitting cream design with black spot by one of her go-to designers, Jenny Packham. The Dress had gathered fan-style ruffles at the shoulder and hip, giving it a 1940s feel. Meghan, meanwhile, opted for a more modern, preppy look in her striped button-down and cream pants by Ralph Lauren.
