School uniform
In this idea, many kids(especially from private schools) are forced to wear school uniform for a reason. Not only does it make their school look tidy and organised, it also helps the children. It trains the children to get used to what is going to happen later on in life e.g. a Job. If you have an office job, would you want to wear skinny jeans and a vulgar t-shirt? No! You want to look formal. Speaking of vulgar, children could bring vulgar shirts or pants to school, thus enhancing the idea of school uniform. For example, panties or any shirt that has "bad words" on it. The school doesn't try to dehumanise the children into robots, they are trying to help them into a well-rounded person by the way they dress.
