In a new photograph issued by Buckingham Palace on Saturday, Charles can be seen smiling wearing a beige jacket and waistcoat alongside the kilt and a traditional brown sporran, while resting his right hand on a pile of books.
The kilt includes green, red and blue stripes and is made from King Charles III tartan, a new variety of the cloth designed by the Scottish Tartans Authority in 2023.
Burns Night celebrates the life and work of poet Robert Burns, who is widely seen as the national poet of Scotland, and is held on the anniversary of his birth in 1759.
The King has championed his passion for Scotland by wearing a tartan kilt to mark the country’s Burns Night celebrations.
Charles’ mother Queen Elizabeth II died at Balmoral in September 2022 while he spent many months at the estate last year following his cancer diagnosis.
