Solution
Such questions are made for enhancing self-creative skills and should be tried
answering on your own. However, here are a few points that will help you in framing
your answer:

• There is no evidence that school uniform has lessened discrimination or bullying. Often quoted better student behaviour is more likely to result from implementing safety rules and regulations. 
• School uniforms signify the socio-economic divisions that they are supposed to undermine. In a single school, wealthy parents buy multiple uniforms for their children, and those of the humble background wear single that might be tattered or faded.
• Most public schools with mandatory uniforms are situated in poor localities while so-called posh schools have flexible uniform policies, emphasising the class division. 
• The push for compulsory uniforms is driven by commercial interests and is an extra expense for the student, in a way discrimination is furthered between those who can afford uniforms and those who can not. 
• Uniforms restrict self expression and promotes conformity rather than individuality.
