Skirts have been banned at a school because the head teacher said girls have repeatedly breached¹ rules by wearing them above the knee.

英国一所学校禁止女生穿裙子，因为校长说女生们再三违反裙子要长及膝盖的规定。

Instead, from September, students at Moulton School and Science College in Northamptonshire will be forced to wear black tailored trousers.

Headteacher Trevor Jones said he has taken the radical² decision in order to fight the 'over-sexualisation' of children.

If they fail to obey the new rule, pupils will be given second-hand³ clothing to wear for the day or sent home to get changed.

Mr Jones said he had seen girls coming into school with skirts halfway⁴ up their thighs⁵（大腿） or even higher.

He added: 'Some of them would be more appropriate in a nightclub than in a classroom.'

'School should be a place where they can come and not have to worry about that for a few hours and instead concentrate on their learning.'

The existing rules had outlined that girls must wear skirts that were knee-length or below, but he said that this rule had been consistently broken.

He added: 'The minimum length was proving impossible to enforce, so we are now looking at a total ban.'

'I have had complaints from a number of parents and some girls are feeling aggrieved⁶（受委屈的） but we think this will make the school a safer place.

The school's website states the rule change, adding: 'School uniform plays a valuable role in contributing to the ethos of a school and setting an appropriate tone.

'It can instil⁷ pride, support positive behaviour and discipline, encourage identity with the school ethos（民族精神，气质） and protect children from social pressures to dress in a particular way.'

The new uniform policy at the school also includes a ban on scarves and hats, unless in cold weather.

Trousers are not allowed to have any non-black stitching or visible metal buttons.
