I think most school uniforms are hideous and unappealing, and being forced to wear something that is not comfortable to a child is not good for their mental image. What happens if someone doesn’t like the colour green, red, yellow, grey or any other colour? If children were allowed to wear their own clothes at least they would be comfortable in it. In the case of younger children, if they got their only school jumper muddy, they wouldn’t have another one to wear the next day, which would mean they got told off at school.
Uniforms make parents spend more money unnecessarily. They are expensive, and parents already have to spend money on clothes for children to wear outside school. If children didn’t have to wear a uniform, parents would definitely have more money to save up to spend on bills, rent, tax and VAT.
People think that if children wore their own clothes, alliances and gangs would form according to social interests, fashion groups etc. I think these gangs or groups will still form even if everyone is wearing uniform; children would be bullied for other things except their clothes, maybe even encouraging racism. Because students are easily recognisable in school uniform, this may also encourage bullying and rivalry between pupils and schools.
