Protecting a girl's modesty? Where have I heard that before...
The school could issue burqas and protect the girls' modesty further.
Also, note the implication that all men are inheritantly perverted, and are desperate to catch a sight of a girl's knickers. And apparently modest should only be persued during winter, as the clothing rules would be relaxed in summer?
He's an idea: how about giving the poor sods at school getting bossed an option, for a change? Let girls wear trousers or skirts depending on what they feel more comfortable in.
