     It is hardly surprising that clothing manufacturers (生产商)follow certain uniform standards for various

features(特征)of clothes.What seems strange,however,is that the standard adopted for women is the

opposite of the one for men.Take a look at the way your clothes button.Men's clothes tend to button

from the right, and women's from the left.Considering most of the world's population-men and women-are

righthanded,the men's standard would appear to make more sense for women.So why do women's clothes

button from the left?

      History really seems to matter here.Buttons first appeared only on the clothes of the rich in the 17th

entury, when rich women were dressed by servants.For the mostly righthanded servants,having women's

shirts button from the  left would be easier.On the other hand, having men's shirts button from the right

made sense, too.Most men dressed themselves,and a sword drawn from the left with the right hand would

be less likely to get caught in the shirt.

      Today women are seldom dressed by servants,but buttoning from the left is still the standard for them.

Is it interesting? Actually, a standard, once set, resists change.At a time when all women's shirts buttoned

from the left,it would have been risky for any single manufacturer to offer women's shirts that buttoned

from the right.After all, women had grown so used to shirts which buttoned from the left and would have

to develop new habits and skills to switch.Besides, some women might have found it socially awkward to

appear in public wearing shirts that buttoned from the right,since anyone who noticed that would believe

they were wearing men's shirts.
