Around 90 per cent of the world’s population is right-handed, and it is easier for right-handers to button shirts from the right. So why do women’s garments button from the left?

This is an example in which history seems to matter. When buttons first appeared in the 17th century, they were seen only on garments of the wealthy. At that time it was the custom for rich men to dress themselves and for women to be dressed by servants.

Having women’s shirts button from the left thus made things easier for the mostly right-handed servants who dressed them. Having men’s shirts button from the right made sense not only because most men dressed themselves, but also because a sword drawn from the left hip with the right hand would be less likely to become caught in the shirt. Today, virtually no women are dressed by servants, so why is buttoning from the left still the norm for women?

In economics, a norm, once established, 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 accustomed to shirts that buttoned from the left and would have to develop new habits and skills to switch.

Beyond that practical difficulty, some women might also have found it socially awkward to appear in public wearing shirts that buttoned from the right, since anyone who noticed would assume they were wearing men’s shirts.
