I was taught, as a child in the '70s and '80s, that only women could wear hats at meals and in church. Later, in the military, it's a rule while in uniform that hats must be worn outdoors and may not be worn indoors unless you are armed.
It still strikes me as very unprofessional when police leave their headwear in the vehicle, and a little "off" when people are eating indoors with hats on.

Not to mention all the hat etiquette in Western countries up until the '60s: https://youtu.be/zePIkXSB1kA
