Granted, this is not your typical sporting event. Markle made her debut on opening day of the Royal Ascot by horse-drawn carriage, riding alongside her new husband as well as his uncle Prince Edward and his wife Sophie, the Countess of Wessex. (FYI: This all went down following a totally casual lunch with the Queen of England). So, essentially, the Royal Ascot makes the Kentucky Derby look like a Monster Truck rally.

Markle paired the sophisticated piece with a small black clutch, matching pumps, a thin black waist belt, and the mother of all hats: a black and white Philip Treacy fascinator that honestly deserves its own zip code.
