A kilt is a garment resembling a wrap-around knee-length skirt, made of twill-woven worsted wool with heavy pleats at the sides and back and traditionally a tartan pattern. Originating in the Scottish Highland dress for men, it is first recorded in the 16th century as the great kilt, a full-length garment whose upper half could be worn as a cloak. The small kilt or modern kilt emerged in the 18th century, and is essentially the bottom half of the great kilt. Since the 19th century, it has become associated with the wider culture of Scotland, and more broadly with Gaelic or Celtic heritage.
