The Prince and Princess of Wales, who are known as the Duke and Duchess of Rothesay when in Scotland, attended the National Service of Thanksgiving and Dedication in Edinburgh on Wednesday.
The event was held to celebrate the coronation of King Charles III and Queen Camilla.
During the service at St Giles' Cathedral, His Majesty was presented with the Honours of Scotland, which are considered the Scottish Crown Jewels. They consist of the Crown, the Sceptre, and the new Elizabeth Sword.
Afterwards, the King and Queen, along with the Duke and Duchess of Rothesay, returned to the Palace of Holyroodhouse. They posed for official photos and witnessed a flypast by the RAF's Red Arrows.
Kate opted for an all-blue ensemble, undoubtedly a nod to the Flag of Scotland.
She wore her customized sapphire blue Catherine Walker 'Mayfair' Coat, a piece she first wore for the Commonwealth Day service in 2022 and then again on Easter Sunday this year.
We saw the return of the unidentified scalloped top clutch and Emmy London 'Rebecca' Suede Pumps in Cobalt Blue, a combination that Kate debuted during last year's royal tour of Belize.
The Duchess wore jewelry with familial connections, adorning herself with the late Queen's Japanese Four-Row Pearl Choker, Princess Diana's Collingwood Pearl Drop Earrings, and her Nigel Milne triple-strand pearl bracelet.
The only new addition to Kate's look today was a blue satin percher hat by Philip Treacy.
