All the royals clearly got the memo, as they wore light blue for the day. The Queen wore a pastel coat dress and a statement hat adorned with fabric flowers.
Meanwhile, the Duchess of Cambridge wore a light blue lace Elie Saab dress, with a full skirt and pussy bow neckline.
She also took a lead out of Meghan Markle’s book by opting for a hat that was very similar to the one the Duchess wore to Trooping the Colour last year: wide-brimmed and worn at an angle.
The Duchess of Sussex was one of the few royals not present at the races, as she is still on maternity leave. Her outing for the Queen’s birthday was a brief exception.
As to the reason everyone wore blue, it could simply be a coincidence, however it’s a colour that has oft been associated with royalty and the military, so it could also be a simple nod to that.
