I can't help but feel it is always seen differently when it is a girl protesting about having to wear skirts and not allowed trousers, when boys wear trousers. It always seems to be "sexist", etc... So why not allow those boys who want to wear shorts, wear them?? What difference does it make in the grand scheme of things?
The school I went to, girls had to wear skirts at a length of between 2 inches below and above the knee, no splits, and not tight. Boys wore trousers all year round.
As long as the shorts, skirts and trousers are the correct colour, I really cannot understand where the problem is...
