Your 1st Paragraph is Irrelevant, however...I argued that...
Children should only have to wear uniform on school event(when vistors come, sports days)
Your 1st Paragraph is Irrelevant, however...I argued that if the uniform is clean then the child could just wear it again, making 5 days. Against your next argument, yes Uniforms are used to represent your school but is also beneficial in many other ways. Firstly, as I stated previously, it lessens the chance of bullying towards clothing worn as everyone will be wearing the same. Secondly it is cost effective and finally it can be passed down to younger siblings or friends.
