Mainly for the ladies: Do you wear leggings as pants or do you always wear long sweaters and tunics over them?

I was today years old when I heard that leggings are only pants when you’re at the gym, which seems ridiculous. If I have an errand to run before or after the gym or any athletic based event I’m not going out of my way to cover my @ss. Hell I don’t even think you need a reason. But I am very accustomed to wearing them in such an athletic way it never occurred to me I shouldn’t wear them anywhere else.
