School Uniforms
No one would need to worry about their child looking as though they are going to a club instead of school, because the appropriate dress requirement would be enforced by teachers. Children would be free to express themselves, and if they wore something inappropriate then they would face the consequences of their actions. In fact, an appropriate dress policy is even better than a uniform code because the students would actually learn something from it. Rather than being told what to wear, students would be responsible for picking their own attire(even if this means getting up earlier for some), and it must be appropriate for an educational environment. This is a life skill that these children are going to be needing further down the road when they need to dress appropriately for work or some other social event. The fact that children are learning something while being able to actively express themselves is a great thing.
