Prince William and Kate Middleton attended the annual Commonwealth Day Service at Westminster Abbey for the first time as the Prince and Princess of Wales.
This follows Queen Elizabeth's death and King Charles' accession to the throne in September.
The couple looked stunning at the event.
Kate's attire paid tribute to both King Charles and Princess Diana.
She wore a navy Erdem peplum jacket and skirt with white embroidery.
Her accessories included a navy fascinator, sapphire and diamond earrings that belonged to Princess Diana, and Queen Alexandra's three feathers brooch, a gift from King Charles.
She tied her hair in a braided low bun and wore subtle makeup. The couple departed after the service.

The Commonwealth Day Service is an annual event held to celebrate the Commonwealth of Nations.
Westminster Abbey has been the venue for the event since 1949.
