I really doubt that anyone told us that Lederhosen and purple bow ties were not suitable schoolwear - I cannot recall any parental comments whatsoever - but the boy who came to my primary school wearing these items in the 1970s had a life that was a pretty hellish, tbh. Your kids are perfectly normally/trendily dressed Twiglett. YOu wouldn't dream of dressing your son in too short trousers and terrible shoes and a beige polo necked sweater tucked in, for example. The boy I saw at the Polka really did stand out, and I know kids will notice. Maybe not at five so much, but certainly at 7. I would love to dress my ds in certain clothes that I think are lovely, but I'm not going to make him stand out any more than he does already. It's not extreme - today he's wearing Sainsbury's jeans and a gap t-shirt and gap coat, and he desperately needs a haircut.
