Black kilts are proposed by some as the traditional version of the garment, some claiming that the Duke of Cornwall's Light Infantry wore black kilts on occasions in the 19th century (this may have been similar to the Irish saffron kilt). The most common kilt used in Cornwall is pleated Scottish-style with a leather, Duchy of Cornwall shield-style, sporran. The Cornish national tartan was designed by E. E Morton Nance in 1963 using colours traditionally associated with Cornwall. Fragments of tartan have been found in Penwith.
