Bottomless at school

Back when I was in grade school (early '70s) the girls in my class often wore dresses that were quite short. One girl that I remember had a brown and white checkered minidress that was EVEN SHORTER than any of the dresses that any of the other girls wore. I remember that the first time (that I recall anyway) when she wore this dress, she wore it with sheer-to-the-waist pantyhose underneath it. I got quite the surprise when she went up on the slide at recess! This girl was NOT wearing any panties underneath that very short dress! I could very easily see her butt when she got to the top of that slide!

I am aware that years later (when she was in high school) she became a cheerleader. No word on if anyone ever checked underneath her skirt to see if she was wearing anything under it!
