For context, school has been terrible about communication so far - not responding to any emails, cancelling a registration day only an hour in advance, etc.
I checked the uniform policy - nothing on website. On the uniform retailer page, there were guidelines, but nothing about boys' trousers and nothing for sale, so I figured there were no restrictions. I bought DS some plain trousers over the summer.
It's now about a week before school starts and a school Whatsapp has been set up. I asked about the uniform just to make sure and a parent with a child already enrolled has replied saying they're only allowed to wear grey uniform trousers from Next or M&S.
It’s too late to return what I bought and I don’t have the funds to buy all new clothes simply because school didn’t bother to tell parents the uniform.
AIBU to send him in in what I bought because there is no information stating differently?
