ELI5: Why do men's clothes have buttons on the right while women's clothes have buttons on the left?
gpt
The general explanation for this is a few hundred years ago it was common for gentlemen to dress themselves while ladies would be dressed by others.  Since right-handedness is by-far the dominant trait, the buttons would be on the right for a man, but on the left for a woman so that for a second woman facing the first, the buttons would be on _her_ right.

With many things, these fashions trickled down to the gentry then just stuck around ever since.
