   There is probably no field of human activity in which our values and lifestyles are shown more clearly and strongly than they are in the clothes that we choose to wear.The dress of an individual is a kind of “sign language” that communicates a set of information and is usually the basis on which immediate impressions are formed.Traditionally,a concern for clothes was considered to be an affair of females,while men took pride in the fact that they were completely lacking in clothes consciousness(意识).

This type of American culture is by degrees changing as man dress takes on greater variety and color.Even as early as 1955,a researcher in Michigan said that men attached rather high importance to the value of clothing in daily life. White collar workers in particular viewed dress as a symbol(象征)of ability,which could be used to impress or influence others,especially in the work situation.The white collar worker was described as extremely concerned about the impression his clothing made on his superiors(上司).Although blue collar workers were less aware(察觉到的)that they might be judged on the basis of their clothing,they recognized that any difference from the accepted pattern of dress would be made fun of by fellow workers.

Since that time,of course,the patterns have changed:the typical office worker may now be wearing the blue shirt,and the laborer a white shirt;but the importance of dress has not become less.Other researchers in recent years have helped to prove its importance in the lives of individuals at various age levels and in different social and economic status groups(阶层).
