My dc have been to both uniform and non-uniform schools and, to my surprise, I prefer the non uniform.
It's not a hassle at all them getting ready in the morning, I let them choose their own clothes, I've only ever vetoed one outfit when my youngest wanted to wear a sun dress in the middle of winter. There was a little boy in her reception class last year that wore a fancy dress costume everyday for the first half term. My dd has also worn her Anna dress to school before.
And there's no bother with finding their school shoes, they can just wear any, I don't have to worry if I hadn't done any laundry or ironing at the weekend. It's a brilliant school with an outstanding ofsted rating, they focus on growth mindset rather than what the kids are wearing.
I'm also not even remotely able to tell which kids come from poor or rich families. We're not poor but my dc live mostly in Primark, H&M and George at Asda.
My eldest is moving to secondary in September and will be going back to a uniform which she is ok with, but (if we get our first choice) it's not as strict as some of the examples on here, and blazers are optional.
