Some high school girls like to roll up their skirts around here. Some of them roll them up super, really high. Some are rolled so high that I can actually see their underwear sticking out when they're walking, and of course when they're sitting.
Some girls don't roll their skirts at all. They hang down to mid-calf. When you see what length the skirts are supposed to be, it's quite impressive how high the other girls have managed to roll their skirts without it looking very bunchy at the waist.
Some girls take the anti-rolling to an even further extreme, and wear track pants under their skirts on the train. I feel like these girls are saying, "Stop looking at me, you perv." I feel a special affection for these girls.
