The traditional pleated skirt worn by Scottish men as national dress is called a kilt.
A traditional kilt is a wraparound garment that usually reaches the knees and is made from wool, often in a tartan pattern. Its pleats are concentrated at the sides and back, while the overlapping front panels form a relatively flat apron. Kilts are commonly worn for weddings, Highland games, dances, ceremonies, and formal Scottish events.
The earliest recorded form was the great kilt, or belted plaid, documented in the Scottish Highlands during the 16th century. It was a full-length piece of cloth whose upper portion could be worn as a cloak. The smaller kilt, closer to the modern garment, emerged during the 18th century.
Tartan patterns are strongly associated with Scottish clans today, but the connection between particular tartans and clans developed over time and is often more complicated than popular tradition suggests. A sporran is frequently worn with a kilt because the garment itself usually has no conventional pockets.
