The school doesn’t force children to dress up. They decide to do something fun and say you can dress up. They don’t say it’s mandatory, it’s the parents that make it into a competition and into something it’s not. It annoys me every year that people come out and moan at schools for doing it. If they stopped then some parents will moan they’re not doing it. Schools can’t win!! They’re not going to say anything to anyone coming in their own clothes or school clothes. It’s only a huge deal if parents make it out to be!
