I was thinking that it must have been a shcool uniform, too. So many girls have their uniform skirts way too short, in my opinion. The girls whose skirts were longer than normal were thought be kind of bad girls about 20 years ago, but I'm not sure if any girls have their skirts long for that reason any more.
I know how you feel, Kirie_Maiden. I think girls should be able to wear pants if they want to even as a uniform, skirts just made my legs damn cold!
