The Royal Stewart Tartan is the tartan of the royal House of Stewart, and is also the personal tartan of Queen Elizabeth II. It is said to be appropriate for all subjects of Elizabeth II to wear the Royal Stewart tartan, much in the same way that clansmen may wear the tartan of their clan chief. Officially, the tartan is worn by numerous military groups, and a select few civilian groups. The 5th Potters Bar Scout Group wear the scarf officially, with permission from the Queen.
