The Princess of Wales brought the sunshine to Royal Ascot after a two-year absence as she arrived at the races wearing a bright yellow dress today.Catherine, 44, joined the family's carriage procession alongside her husband, the Prince of Wales, today. The future Queen's canary yellow outfit is from the label Roksanda, and Catherine paired it with a matching hat, while Prince William pinned yellow flowers to his lapel in a sweet, matching moment. This is the third time Catherine has donned the frock, having previously worn it during a state visit to Jamaica and Wimbledon in 2022. Racegoers were delighted to see the Princess riding in the second royal carriage alongside Prince William, 43, after she was forced to skip the event in 2025 while trying to 'find the right balance' after her cancer treatment. They were accompanied by the Duke and Duchess of Richmond and Gordon, riding behind King Charles and Queen Camilla in the first carriage. The last time Catherine attended Ascot was in 2023, when the future Queen famously wore a 'tomato red' Alexander McQueen dress - proving Kate is always one step ahead of fashion trends.

She paired the designer dress with a matching hat and shoes, both from Emmy London, as Carole happily posed for pictures alongside Alizee.

Catherine announced she is in remission from cancer last January as she embarked on a gradual and measured return to public duties.
