Nobody "dresscoded" me at home. As soon as I was old enough to pick my own clothing, I could. What skirts or jeans or dresses I wore was my choice completely. My school also didn't care much.
Blew my mind when I realized how many other girls had to sneak out with their clothes because the parents had a rule against tight jeans or whatever.
I still think my parents were right with this one. The kids with the strictest rules were always those with the craziest outfits. Can't blame them, I'd have done the same.
Don't do this to your kids if you think that was wrong, lol. I know people who grew up like this, complained to me and then started to behave the exact same way with their kids later on.
