Image 5/9 for "Japanese School Girl Skirts"

Folks who run schools are generally not happy about the short skirts and want them extended to default length.
The reasons they give are things like the girls getting ill from catching a cold (from wearing short skirts) and because of some incidents where some girls had their skirts cut by perverts.

The skirt on right is a standard skirt but the one he left has been developed to stop the girls from rolling up their skirts by making the whole skirt messy after a rollup attempt.
