The kilt is more than just a covering. It allowed those who wore it to move much more freely, especially in the Highlands of Scotland where the weather can become very damp. With its tight weave of strong wool, it created a barrier between the rain and skin. When the armies of the past were fighting in Scotland, the kilt with its pleat helped protect the soldier much like armor would. When the nights became cold, this garment was easily removed and spread out to create a blanket to keep the person who owned it warm. Lastly, if the army needed to move with a much quicker force, the garment could be easily removed, thus allowing the soldier more freedom of movement.
Today the kilt is the national dress of Scotland and worn by many. The various plaids that one can see from time to time are the colors of the particular clan that the wearer belongs to. It is much shorter than the ones worn by the Highland armies of yore, but still evokes the pride that was carried by those who lived above the land of Scotland.
