ELI5:Why are dresses and skirts traditionally considered feminine, while pants are traditionally considered masculine?
gpt
Men began wearing pants regularly when horses and horse riding became one of the main methods of transportation, hunting and waging war.  It was rare that women would take on these roles, certain cultures and tribes notwithstanding.  What rose from necessity and practicality, eventually became the norm and the tradition for men and women.

From a woman's point of view, skirts and dresses were probably more convenient in some ways as well, especially for whenever women were having their courses or relieving themselves and for pregnancy and giving birth.
