Will children be "insecure and have complexes because they can't wear what they want"? Please. What nonsense. A child needs to be psychologically stable enough just to attend school. Therefore, if someone develops complexes because of such trivial things, life will be difficult for them anyway. Moreover, children can wear whatever they want after school.
Of course, many people don't like uniforms, and that's normal. But to develop complexes because of this is an exaggeration.
