I'm several years out of the education system and fuck that noise. I'd be interested to see your studies, as a kid I faced mild bullying and always wore cheap clothes but there was never a causal link.

To me this uniform craze is 20 % well-intentioned-but-mostly-useless and 80 % old reactionaries trying to gain a sense of control over the youth (and society in general) which is just another symptom of the societal illness that is bringing back fascism (not that uniforms are inherently fascist... but fascists LOVE uniforms).
