Based on the Duke of Rothesay, Hunting tartan. James Cant's note for Prince of Wales states, "This tartan, along with the red form, was issued by the Vyella Co. It was originally meant for the Rothesay, but the division showing the single white line was omitted by mistake. Instead of withdrawing the material, the pattern was given the name 'Prince of Wales'."
This is a universal tartan, designed for ANYONE to wear. It was registered in 1998.
