It is called a kilt The Scottish like to be different. They are also proud of their country and its history. and they feel that the kilt is a part of that ほこリにう history. That's why (nthe men still wear kilts at old-style dances and on national 5 holidays. They believe they are wearing the same clothes that Scottish men always used to wear. That's what they believe. However. kilts are not really so old. Before 1730, Scottish men wore a long shirt and blanket around their shoulders. These clothes (2)got in the way when the men started to work in factories. So, in 1730 a factory owner changed 10 the blanket into a skirt: the kilt. That's how the first kilt was made. Then, in the late 1700s Scottish soldiers in the British Army began to wear kilts. One reason for (3this was national feeling: the Scottish soldiers wanted to look different from the English soldiers. The Scottish soldiers fought very hard and became famous. The kilt was part of that fame, and in the early 1800s men all around Scotland began 15 to wear kilts. laThese kilts hadcolorful stripes going up and down and across. Scottish people often believe that the colors of the kilts are part of their family history. In fact, each family just chose the colors they liked best in the late 1800s. This is not the story you will hear today if you are in Scotland. Most Scottish people 20 still believe that kilts are as old as Scotland and that the colors are as old as the Scottish families. Sometimes feelings are stronger than facts! (287 words)
