Cornish kilts and tartans are thought to be a modern tradition started in the early to mid 20th century. The first modern kilt was plain black, and other patterns followed. It is documented that a garment known as a bracca (a reddish checkered tunic) was worn by Celtic people who inhabited the British Isles, the term indicating its appearance. The Welsh word brech means "checkered" (compare the cognate Scottish Gaelic breac, "variegated, freckled"), and the word bracca is derived from the Welsh or Cornish word brythen which in English translates as "striped" or "checkered".
