It’s not just women who wear skirts. Men can wear them, too. In Scotland, men wear a kind of skirt called a kilt. The kilt is their national dress and an important part of their tradition.

A kilt is a coloured skirt reaching down to the knee. It has checks(格子)on it with different colours, like red or blue. Each family in Scotland had its own colours.

How did the Scots start to wear kilts? There are many stories about it. One story is that the kilt was invented in the 1720s by an English factory owner, Thomas Rawlinson.

Rawlinson has a number of Scottish workers in his factory and he thought their clothing got in the way of their work. So he cut their long clothes into a shorter skirt.

Today, most Scotsmen see kilts as formal(正式的)dress. They usually only wear them at weddings or big dinners. There are only a few men who still wear a kilt every day.

Scots also wear kilts in parades when they play their traditional musical instrument:bagpipes(风笛). The army still has kilts as the dress uniform. but they no longer wear them to fight.
