Before the jeans revolution of the 1960s it was quite rare to see a woman wearing trousers, except maybe as slacks for a party.
A lady once told me during WW2 that you could easily detect a spy, dressed up as a woman in a skirt. You just sat them down and then threw them a ball. If their knees snapped together it was obviously a man. A woman would spread her skirt to catch the ball.
I have noticed that if I drop something while I am working, even though I wear an apron, my knees snap together. How is it for you? Dennis.
