[originaltext] In nearly all civilizations, at nearly all times in history,

In nearly all civilizations, at nearly all times in history, men have dressed differently from women. But it has not always been a simple matter of men wearing trousers while women wear skirts. In Scotland and parts of the Far East, men as well as women wore skirts. In Turkey and China, and among Eskimos, both men and women wore trousers. But in ancient Greece men who wore trousers were thought to be little better than savages.
    We think of women as wearing brighter clothes than men. Yet in some historical periods, it was men who wore the more colorful and elaborate costumes.
    Some anthropologists believe that the clothing men wear is directly related to the position they hold in society. In many civilizations, kings and chiefs wore special clothing and headgear to show their authority. Rich, important men in the 18th century wore special clothing, often elaborately made and difficult to keep clean. Since poor men could not afford to wear this kind of clothing, it became a symbol of wealth.
    Even today, men wear clothing that symbolizes their positions in life more often than women do. Men sometimes wear jewelry marked with the insignia of organizations to which they belong. Soldiers, delivery men, and service station workers wear uniforms. Doctors and dentists usually wear white coats.
    Women wear clothes to make them appear more attractive. As the fashion in beauty for women changes, clothing for women has changed rapidly.
    Men and women think alike about some things. But they don’t always agree about clothing.
