I remember when I was a freshman at a Catholic high school fifty years ago, the nuns used to get exercised about girls with skirt hems above the knees and blouses with unbuttoned top button. I still remember one ancient nun declaiming to the class that nobody wanted to see the girls’ “knobby” knees. All the boys, like me, just bit our tongues.
That was Sister Cleopha, the NO-NONSENSE math teacher, at Mount Carmel Junior High in Denver, Co ca. October, 1970; at the start of the school year for some period of time the girls were exempt from wearing uniforms (I guess so they all had a chance to purchase them or whatever); said sister commented ‘I will be so glad when you are all in uniforms, I am so sick of seeing BARE HIDES!’...I wasn’t sick of it at all lol!
