Academies are trying to emulate private schools with plaid skirts/pinafores, blazers, ties and draconian rules
That would explain the hideous yellow and burgundy check skirts I see when passing a school on the way to work.
I agree with the idea of a school uniform, its a leveller and school is not a fashion parade etc.
Include blazers, jumpers, long and short sleeve shirts, trousers, skirts (with obvious caveat re length) and even smartish knee length shorts, but leave the choice of what is worn when to the individual student - some people are hot and cold at different temperatures and what is right for one is not for everyone.
It's stupid wrong and possibly dangerous to enforce the wearing of blazers in this weather, just like it is ridiculous to require boys to wear short shorts in winter, like some private schools (used to?) do.
It's the permitted selection of garments thats the 'uniform' not the rigid requirement to wear all of them at all times.
