When I started Secondary School in the mid 60s stockings were still part of our uniform, tights had only just become more commonplace. When we had to walk up to our Science Labs the staircases were open, boys used to stand at the bottom to see if they could see up our skirts
, we used to stop & shout down to them, they soon got bored. Trousers for girls were not part of the uniform in those days.
I wore mini skirts & hot pants (not at School), inappropriate behaviour was dealt with usually by a "look" or even a slap, are girls/women more sensitive these days or has sexual harassment got worse?
