Glen plaid refers to a plaid pattern with a woven twill design that features small and large checks. Its name is derived from the valley of Glenurquhart in Inverness-shire, Scotland, where it first originated in the 19th century as a checked woolen fabric. The pattern most often features a crossing pattern of irregular checks, that is created by a series of alternating dark and light stripes. Glen plaid is typically rendered in black, grey, and white.
