What kind of new-fangled educational philosophy are you trying to promote here?
This is why I think Catholic Schools have the right idea with uniforms. Even back in my school days, the question was often raised in the Catholic schools as to whether or not uniforms were a good idea. I always appreciated them: everyone is on the same level; you don’t have to think about what to wear every single day; you don’t encourage judging others based on external appearances; you are encouraged to express your individuality through thoughts and actions rather than mere externals; etc.
