I think uniforms are stupid. I was training as a primary teacher just as the fad for putting primary aged kids back into uniform - after decades of not having it - came back. And that was long before I was a parent, but even then I thought it was crazy. Uniforms never look good anyway - cheap synthetic fabrics, etc. My kids freeze in winter.
Recently, I was on a FB group about the history of my old primary school and someone posted class photos from late Victorian times up to the 1970s when the school closed. We were the last kids there. And even in Victorian and Edwardian times - no such thing as a uniform in a village primary school. But many parents are in their 30s and probably now don't remember a time when kids didn't wear it so they imagine it is traditional. It's not. Not in ordinary state (primary) schools. Secondary schools often had it.
It's impractical, cold, expensive for what it is (nylon tat) and in the case of this area, only one or two shops allowed to stock it so you have no choice - it's a monopoly and they can charge £12 for a 50p thin, synthetic jumper because if you have no alternative "That's what the market stands".
I think it's another of those half baked tory 'reforms' that came in the 1980s - some fantasy of this perfect little England, where kids would be future employers' drones so better learn to conform aged 4.
Costs me money I don't have and my kids would be more comfortable and warmer (or cooler, in summer) wearing their own clothes. I think maybe parents at the time it was reintroduced thought it was 'A Good Thing' - but since when were parents educators?
