Women’s and men’s shirts and jackets differ not just in terms of how they’re cut, but also in how they’re oriented: To the person wearing them, men’s dress shirts have their buttons on the right, while women’s have them on the left.

There are different theories as to why the discrepancy exists in the first place, but all of them come down to this: The Button Differential is a relic of an old tradition that we have ported, rather unthinkingly, into the contemporary world.
