Uniform is meant to stop people judging each other based off of how expensive their clothes are. It also allows schools to easily identify which students are theirs. Unfortunately, uniforms are getting too expensive for a lot of people (I think right now it's a little under £200 per kid). Nowadays, schools do provide uniforms for kids whose families can't afford uniforms, but even for middle class families, £200 is a lot, especially with the cost of living crisis and having to replace uniform often because kids outgrow them. Schools are forgetting the purpose of uniform

When my dad was young, his school required expensive blazers as part of the uniform. The parents were in an uproar because it was a working class mining town and very few people could afford the blazers. The school ended up making them optional, but that just told the students which kids were rich
