Meghan selected one of Kate Middleton's go-to brands, Goat, to attend Prince Charles's 70th birthday party at Buckingham Palace. It was her accessories — a Philip Treacy hat, Tamara Mellon pumps, and a Wilbur & Gussie clutch with a sheen — that brought out the pink in her outfit. She completed her elegant ensemble with Vanessa Tugendhaft Idylle earrings.
