Do conservative in other countries also push for school uniforms ?

Ive also been to school in countries with and without and I find that absolutely none of the good things people attribute to school uniforms are true.

1. No pressure to dress well. Except that either a) you can buy better or cheaper fabric school uniform or b) the school makes new designs every year or two of the uniform and students that cant afford to buy new clothes every year or are buying second hand are easy to pick out.
2. What about earrings, rings, hairstyles. School uniform shoes need to usually be bought from outside of the school and those come at just as many price points as normal shoes.
3. I guess thats true
4. This totally depends on the school you're going to and what you personally like. If you are going to a fancy private school then you might have to wear a tie a lot which could be annoying to some. My sister had to wear skirts that went to her ankles which she didnt like. I was in a public primary school so you could wear pretty much whatever you wanted as long as the colours were correct which makes me pretty lucky. In the best case, you arent restricted but that often isnt the case once you are done with primary school. If you can buy your own clothes you can always pick something that fits you and is made from material you like.
5. And stupid for enbys that are still finding themselves when uniforms are clearly for men or for women. Its much easier to find something that suits you personally if you can pick from everything instead of a reduced set that forces everyone to fit into one of two groups.
6. Wardrobe malfunctions are less likely to happen if you dont need a whole second wardrobe for things you only wear to school and take off immediately when you come home.
7. Kids can reuse hand me downs in any case.
8. You can recognize your friends just fine without the uniform. Youre also not likely to wear the uniform outside of the school, because if you do anything that isnt perfectly exemplary behaviour while in school uniform and a teacher gets wind of it (and believe me this happens in the suburbs) then you (apparently) tarnished the school's reputation forever. Also, you take it off because its ugly and because you dont have a lot of it and have to make it last before it goes in the laundry.
9. Maybe from a distance? Up close people can very easily tell what your body type is.

There is absolutely no merit for school uniform. They're exhausting to deal with. They kill your self expression which is important for teenagers especially. Often schools take it too far and try to send the pupils back into the 17th century. My sister wasnt allowed to wear make up. If you were seen with make up there were wet wipes at the front of every classroom so the whole class could see you wipe off your makeup. School uniform socks are just a greedy money making scheme.

And most importantly, they dont do anything against bullying. Kids dont bully each other for clothes because they actually mind the clothes. They bully because they want to bully. There will always be something. And there are better ways to work against that than forcing all children to buy a second wardrobe and suffocate anyone who is trying to express themselves in an unconvential way.

Total tosh. Those are the dogmatic points people have been rolling out for years without any basis in fact. The "great leveler" theory was useful post War when the differences were obvious, but they are largely irrelevant today.

The "Sense of community" is always translated by kids as "forced to conform to what their parents did". They don't want that, and frankly most people who want to feel free to express themselves don't want it either. The wardrobe malfunction stuff is true for uniforms as well, especially if you are a 14yo girl (parents of daughters will understand). The same is true for basically all of the points you made. And body image problems are often made a lot worse by NOT having freedom to choose what you want to wear. Also, studies looking at uniform vs educational outcomes have never found statistical meaningful correlations for our against uniforms.

These days schools in the UK only have uniforms due to a tradition introduced for reasons no longer relevant today.

Tldr: uniforms are an anachronism, used as means of constraining and controlling kids, and reminding them who is in charge.

Very long; reading if you like:

Using uniforms to disguise the differences between rich and poor was a post War idea that made a lot of sense in the UK. The introduction of public schools at the time brought kids together from a wide range of backgrounds just when those differences were very obvious. It all made a lot of sense. Also, English private schools had famously used uniforms as it created a certain image that they wanted. To a degree this is now true of public schools, and the "tradition" of wearing uniforms is often given as a reason to keep them.

In the UK, in 2024, there are always kids wearing uniforms that are unwashed, need repairing, or just the wrong size. But even without those signs the kids all know who is rich and who is not.

If you take kids out of their uniforms and let them wear their preferred clothes, the differences between become very hard to spot. Back in 1942 this was not true, but today you'd be hard pushed to tell who is rich and who is not making the original purpose irrelevant.

To setup a study of the impact of uniforms is logistically impossible, however all studies that look at educational outcomes found no correlation between uniform and exam results. This seems to disprove the claim that uniforms allow kids to do better in class.

Today, schools like to have uniforms for a few reasons. One, they claim it is part of the school identity, which is true to a degree. But it came about due to national hardship, and is a reminder of times we no longer need. Two, school rules on uniforms have always existed but have become more strict in recent years (speaking as a UK parent of 3 kids aged 12, 16, & 25). In the school my kids attend(ed), they will send letters home and punish kids for uniform related infractions the moment they happen. However, they don't do the same for education related issues. It took 2 years for them to report the issues my daughter was having, and they seemed more concerned with her earnings than her school work when we spoke with them.

Dropping uniforms would reduce the load on teachers who would not need to constantly monitor and punish kids for wearing the wrong shoes, or coats, or bags, or having earrings even. There would still be some rules but they would allow far more latitude for self expression and freedom that kids in 2024 require. And this is an important point. For good or bad, modern children are exposed to information, news, behaviours, and attitudes from around the world, from a very early age. They are also going through the universal issues of adolescence. We need to accept they need freedom to express themselves, not find ways to constrain them.

On a side note, it is my own view that some schools are scared of giving kids freedom to choose, and the uniform rules are intended as a way to make them "conform" to a conservative standard. Uniform rules are effectively a stick they can smack kids with. Take it away and you take their power.

School provided uniforms

Don't exist in my experience...

I've heard the socioeconomic differences thing many, many times, and have kids that wear uniform. But I've never understood that argument.

It conceals socioeconomic differences. Which in the case of economic differences, is probably not egalitarian, strictly speaking? Ditto for social "class" in the sense of whether the family is historically "monied" and has particular dress style. In the case of cultural or ethnic differences, I do not see how the egalitarian logic follows either, as freely expressing your identity is restrained.

In terms of bullying... in my experience bullies will always bully. They will just do it on your overcoat, or how old your uniform is, or your earrings, or your accent, or the colour of your hair. I don't know, maybe the uniform helps a bit...

It also stops pupils from being singled out for not being able to afford expensive clothing, apparently.

I thought this was already the norm in France.

I am not that old, but the only school I knew with uniform was the all girl catholic school in my french hometown. And I believe a few years back, even them stopped having an uniform (and even merged some classes -for the older students- with the "all boy catholic source which never had an uniform").

So until the experiment to be started in public school, it was very rare in France

How odd to think what a 10 year old wears to school is a political statement!

It is in America. But then again, you guys are a century or two ahead of us.

Is the cost of the uniforms on the students or institutions?
