I did see a picture of a schoolgirl wearing ankle grazer type trousers who was admonished for showing her ankles, I think she was told they could be deemed some sort of "sexual turn on" good grief! clearly in the mind of someone who is back in the 1890s 
Another waist roller here, as short as we could get away with, outside of school, the nuns at my convent were of the opinion that patent shoes some sort of deviant/sinner's footwear, one's knickers could be seen in them allegedly! I think one smart arse said "oh well I just won't wear them then" the nun who was advising us on the appropriateness of our footwear was temporarily speechless, trying to work out whether "I won't wear them" referred to the shoes or her knickers 
My friend was told the same by nuns about patent leather shoes, they were also told to sit on a telephone directory if sitting on a boy's lap. We all fell about when she told us, imagine people going to a dance or party with a telephone directory.
At our school, we had to kneel on the floor and our skirts had to touch it as did our divided skirt shorts. Under which we had to show our navy knickers by hanging from the wall bars. A friend had the class in an uproar when her mother had managed to get her a pair with pockets in and she insisted on lifting her skirt to get her hanky out of her pocket.
I was personally reprimanded for wearing flesh-coloured tights which left too much to the imagination. My mother had got a job lot cheap from the Co op and would not buy me some darker ones. So I had to revert to the old knees socks which were bright red!!! Of course, they didn't insite any boys the school was co_ed, especially when you had your skirt turned over three times aged 18. They were school uniform.
