When it comes to a day at the royal ascot, hats are always the star of the show.
Earlier today, Kate Middleton joined Queen Elizabeth II and Prince William for day one of the Royal Ascot at Ascot Racecourse.
While royal watchers loved the Duchess of Cambridge's Ellie Saab dress with long sleeves, many eyes went straight to the hat that couldn't be missed.
E! News has learned Philip Treacy was the designer behind the floral accessory that complemented her look perfectly.
Despite the rain, thousands of racegoers were treated to the sight of senior royals processing in carriages along the famous Berkshire course to mark the start of the event. In fact, the only immediate family members missing with Prince Harry and Meghan Markle who were looking after their six-week-old baby Archie.
The Royal Ascot is as much a social and fashion occasion as it is a sporting event. From summer dresses to sharp suits, everyone looks their best. But perhaps the greatest piece of fashion around the event is the hats.
Take a look at just some of the wild and creative looks from the royal ascot in our gallery below.
Don't forget royal watchers! We're only at day one of the festivities. In other words, more hats to come!
