Personally, I think that the uniform is the great leveler. It makes things way simpler for the parents - most of whom are both working full time jobs. And it removes the competitiveness around wearing the latest designer/expensive whatever's which tends to unfairly stigmatize kids from low SES families.
I am 100 percent in favour myself.
That is the other reason that is quoted as well is as it is cheaper in the long run. My personal experience is that old ill-fitting uniforms are more obvious than the mix of second hand, cheap stuff and occasional splurge sale item that most poor kids i know wear. Also when i was a teenager i only had two shirts which meant one of them often had to be worn several days in a row.
They are cheaper IF you usually buy new, full price clothes and name brands.
They are a leveller IF everyone can afford sufficient, well fitting, new or second hand items.
