Based on prices of uniforms 25-30 years ago compared to wages, uniforms and shoes , and clothing in general is a lot cheaper these days. But the problem is that many uniforms are outdated in terms of design and comfort. I think everyone wearing the same clothing has many different advantages at that age. Infact when I was at school wearing a uniform made things so much easier. The only thing is that it wasn't very comfortable, and could be too cold on cold days. eg having to wear shorts in winter or cold weather.
