Middleton — who scaled her royal schedule back last year due to her cancer diagnosis — joined Prince William, King Charles, Queen Camilla, Princess Anne, Prince Richard, Duke of Gloucester and Birgitte, the Duchess of Gloucester, for the commemoration.

The Princess of Wales joined members of the royal family at Westminster Abbey on Monday, March 10, to celebrate Commonwealth Day. As part of the service, Kate and Prince William processed behind King Charles and Queen Camilla. They were followed by Anne, Princess Royal, as well as the Duke and Duchess of Gloucester.

Royal watchers have been quick to express their upset after a post shared on the royal family's official Instagram account failed to mention the Princess of Wales

Kate Middleton is back at the Commonwealth Day Service after missing it last year before announcing that she was undergoing treatment for cancer.

Kate Middleton's return to the Commonwealth Day celebrations on Monday, March 10, was a masterclass in royal symbolism and sartorial elegance.

The Princess of Wales wore a bright red bow-trimmed dress, pillbox hat and some meaningful jewelry for the annual celebration.

It’s not the first time Kate, 43, has worn the Beau Tie dress for major occasions. She wore the same dress for the Together at Christmas carol service in December 2022, and again in November 2023 for the South Korean’s president state visit.

The Princess of Wales honored her father-in-law, King Charles, in the traditional way and made a subtle homage to Queen Elizabeth during Monday’s church service.
