The Duke and Duchess of Sussex couldn't contain their happiness during their wedding ceremony — and understandably so! They were surrounded by their loved ones, close friends, and 1,200 lucky members of the public as they exchanged "I dos" in St. George's Chapel at Windsor Castle. Meghan wore a stunning white gown by Clare Waight Keller for Givenchy for her big day, while Harry suited up in the frock coat uniform of the Blues and Royals.
