Why do schools feel the need to implement uniform rules on additional clothing to combat the cold?

[FindingMeno]

With doors and windows open to try to reduce covid infection this Spring term, why on earth are uniform rules being implemented on additional clothing?
Specific guidelines on the types of coats that may be worn in class. No hats, scarves, gloves. And not to mention the colours allowed for face masks.
Are all schools like this? Does anyone understand the reasoning?
Or is this just an example of schools putting in place unnecessary rules just because they can?
Obviously I understand some extremes may not be acceptable, but, really, is the wrong colour coat or face mask a big deal given the times we're living in?

this. Schools feel that they need rules for the tiny things, so the rules for the big things get adhered to. I am not convinced that kids adhere to petty rules - I think a lot of the time, if they see the need for a rule, they will generally comply. But not when it's petty. But obviously most headteachers disagree with me.

So wearing a face mask, yes. Wearing a face mask in navy, no. Any colour will do and I would tell the school my child was wearing whatever was clean that day,

Update.
I've just had a shirty email back from the HOY saying by allowing coats hats and scarves they are being flexible about uniform and that boots are not allowed.

Utterly pointless, a waste of time, unnecessary stress on kids who have to sit in cold classrooms, and families who quite frankly have enough shit to deal with.

@Fizbosshoes unfortunately I'm unsurprised.

The point of having a uniform is to be reasonably uniform. You could argue that nowhere should ever have a uniform because it would always be possible to do whatever in other clothes. But still they persists- for ease, for sense of belonging, for identity. None of which have become less because if the pandemic.

Specifying colour is fine. How far they specify coats is OK if it's reasonable (I'm guessing they're not emulating private schools which sell for own supplier or specify brand/style)

How can it be easier to have to go off and buy a separate mask/scarf etc in a school-approved colour? And do children seriously have less of a sense of belonging just because their mate has a different hat on?

Most materially, how do all those schools in other countries manage with no uniform at all? They seem to have no problem whatsoever with establishing whatever sense of belonging and identity they want.

Unbelievable! The children must be able to wear what keeps them warm. For one thing, they are more likely to get sick if they are cold. I find this kind of thing petty and disrespectful of the children as individuals with different needs.
