Another day, another Givenchy dress! The Duchess of Sussex doubled down on her love of long, flowy frocks today at her Royal Ascot debut in a button-down shirtdress by her wedding gown designer. Meghan Markle and Prince Harry joined Queen Elizabeth for lunch to celebrate the first day of the horse race, then took a carriage ride onto the course with Prince Edward and Sophie, the Countess of Wessex (just another day in the life, right?). Meghan donned her elegant LWD with a Philip Treacy hat and accented the look with sharp black accessories, including a skinny belt, pointy pumps, and a minaudière clutch.
