During my first year of High School (1970), mini-skirts were still popular (well, mini-skirts or long hippy dresses -- depended on which social group you belonged to). But in any case -- dresses were not optional for school wear.
Not only did girls have to wear dresses to school, regardless of Kansas blizzards and sub-zero temperatures (Broce spoke recently in a comment thread about an experience I remember well -- wearing pants under my skirt to the bus-stop where we stood in the freezing cold until the bus came, and then having to take them off before I could board the drafty, unheated school-bus), but in my freshman year, the principal decided it was time to crack down on all us slutty girls who were wearing our skirts too short.
This crack-down resulted in a new morning routine at the school entry -- as the boys skimmed past us (the principal giving them only a cursory glance to make sure that their hair wasn't "on the collar"), all the girls in my school lined up on the stairs, the queue inching upward slowly, as, one by one, we knelt in front of His Majesty Assholyness at the top of the stairs, to assure that our hems touched the floor. (Of course, we would roll our skirt-tops up later, but only if Mr. Badass was not prowling the halls.)
At the time, I didn't really understand what I was feeling -- I didn't know that the crumbling, compressed sense of tinyness that I experienced at the beginning of every school-day that year was. . . . . humiliation. Humiliation that I had somehow earned -- because I was female.
I also did not understand that this ritual was meant to enforce that humiliation -- to burn upon my consciousness the fact that I would be obedient and compliant and kneel and face the crotch of my overlord every day as if it were the most usual thing in the world -- because it was a most reasonable request, after all -- because it was done for my own safety, so that my slutty short skirt didn't get me into "trouble".
My intellect didn't understand all of the nasty nooks and crannies of this ritual, but my psyche sensed it.
