阅读理解 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 form the left. Considering most of the word's population----men and women----are right-handed, 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 century, when rich women were dressed by servants. For the mostly right-handed servants, having women's shirts button from the left would be easier. On the other hand, having men's shirts button form 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 form 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 form 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. 1.
