     If women are mercilessly exploited (剥削) year after year, they have only themselves to blame.

Because they tremble at the thought of being seen in public in clothes that are out of fashion, they are

always taken advantage of by the designers and the big stores. Clothes which have been worn only a

few times have to be put aside because of the change of fashion. When you come to think of it, only a

woman is capable of standing in front of a wardrobe (衣柜) packed full of clothes and announcing

sadly that she has nothing to wear.

     Changing fashions are nothing more than the intentional creation of waste. Many women spend vast

sums of money each year to replace clothes that have hardly been worn. Women who cannot afford to

throw away clothing in this way, waste hours of their time changing the dresses they have. Skirts are

lengthened or shortened; neck-lines are lowered or raised, and so on.

     No one can say that the fashion industry contributes anything really important to society. Fashion

designers are rarely concerned with vital things like warmth, comfort and durability (耐用).They are

only interested in outward appearance and they take advantage of the fact that women will put up with

any amount of discomfort, as long as they look right. There can hardly be a man who hasn't at some

time in his life smiled at the sight of a woman shaking in a thin dress on a winter day, or carefully picking

her way through deep snow in high heeled shoes.

     When comparing men and women in the matter of fashion, the conclusions to be drawn are obvious.

Do the constantly changing fashions of women's clothes, one wonders, reflect basic qualities of

inconstancy (易变) and instability?Men are too clever to let themselves be cheated by fashion designers.

Do their unchanging styles of dress reflect basic qualities of stability and reliability?That is for you to

decide.
