When I was in 8th grade I had a required class called "Deportment." The class was for girls only. We were taught how to walk "like a lady" by having to walk the length of the classroom balancing a textbook on our head. We were also taught that our slips should be exactly 1/2 inch shorter than our skirts - and, yes, this was checked. Funniest thing was that this class was taught by a man - who also happened to be the gym teacher. Read into this whatever you will - and you'll probably be right
