The Kilt

One aspect of British culture - more specifically Scopttish culture - that often makes foreigners smile is the use of kilts, that is, skirts that can be worn by both men and women. Typically associated with Scotland, the kilt was also worn in ancient times by people living in various parts of northern Europe. 
The word kilt derives from the Old NOrse (the language spoken by Svandinavians in the 8th century) kjilt, which means "pleated", from a pleated garment similar to the kilt that the Viking settlers used to wear. From that derived the Scots word kilt, meaning "tucked around the body". 

Today, there are still people who wear a kilt in day-to-day life, but most people tend to save them for special occasions, like weddings and important celebrations.
