At my middle school we had a PE teacher that banned PE skirts, this is the 70's, and made everyone strip naked, no exceptions, and when we tried to put towels to cover ourselves in showers she ripped them down and constantly watching, and when we had forgot out PE kit we had to wear baggy green knickers, now this was not the worst as if you were very lucky you could keep your knickers on and tuck them in but if spotted you were made to do PE while still trying to keep them up, one day she made a kid, who had a bladder problem, to run round the track in front of the boys just in her own pants, no one else, just her, she cried all the way round while the boys stud and laughed. I bet she is still in therapy. I thought later that she was perverted, I don't like to accuse and as I'm mentioning no names so I suppose it does not matter, but when she came into my work one day I REALLY wanted to kill her.
I certainly think on the whole it's not like this now.
