ELI5: Where did the social expectation of only girls wearing dresses come from?
gpt
About three thousand years ago, when the fashion was robes (because technology) men who were going into the field to work, or going to battle would "gird up their loins" by taking the hems of their robes, and tying them up around their legs like pants. This continued for quite a while, the styles started to change, robes became dresses over time, and pants became the norm for those that went out to work and fight. Being that peasant women stayed on the homestead for a majority of their lifetimes, there was no need for pants.
