The royal newlyweds appeared at their first official event, just three days after their wedding took the world by storm. The Duke and Duchess of Sussex attended a garden party to celebrate the 70th birthday of Meghan Markle’s father-in-law, Prince Charles, at Buckingham Palace. Markle wore an understated cream dress with sheer mesh sleeves and a matching hat. Prince Harry spoke to the audience about his father, who will one day become the King of England.
