Kilts originated in Scotland, specifically in the Scottish Highlands during the 16th century. Traditionally worn by men and boys, the kilt is a skirt-like garment with pleats at the back, made from woolen cloth in a tartan pattern. While kilts have since become associated with both Scottish and Gaelic cultures, they were historically a Scottish invention. In Ireland, kilts were later adopted as a symbol of national pride and are often worn in solid colors or unique Irish tartans representing counties or families.
