I'm under 40yo so I'm definitely not "old" or out of touch with the times.
I went to a catholic school and girls would get warnings for hiking their kilts up too high. Our female Vice-Principal use to walk around the school with a ruler and made sure it wasn't more than 3inches above the knee.
Yeah we had girls in tight tops, tight pants, etc back in the day, but you didn't have this curvaceous offering like we do today.
The only thing missing from this ass is a sign saying "ENTER".................... And this is regular and tame for today's standards.
