Prince and Princess of Wales attended Commonwealth Day Service with other royals at Westminster Abbey.

The couple wore elegant navy blue coordinated outfits.

Kate's outfit was composed of a peplum blazer and a matching midi skirt with a floral print.

She wore a blue suede hat, clutch, gloves, and pointed-toe pumps to complement her outfit.

Kate also wore her sapphire-and-diamond engagement ring and Princess Diana's iconic sapphire-and-diamond earrings.

She wore the Queen Alexandra's Three Feathers Brooch, a piece worn by past Princesses of Wales, including Princess Diana.

Prince William wore an all-blue look, which included a navy suit, a white shirt, a cornflower blue tie, and black dress shoes.

Photos show the couple standing directly behind The King and Queen Consort.

The Queen Consort wore a bright cobalt blue coat dress with a matching hat, tights, pumps, and clutch.
