Isn't it always the way, that those who are really well off are happy to choose second hand, or to buy good quality and then to use it and use it until it is absolutely threadbare. Parents in independent schools are often very happy to use the second hand or thrift shop and to tell everyone. Having everything new is seen as a bit....nouveau!
I hate to agree with this because it feels more like a recycled MN urban legend than the truth, but it is actually the truth. My kids have both gone to a London prep and the second-hand sales are absolutely heaving (and they're 1x per term, and further broken down by older and younger sizes). They need about 20 volunteers to run it. Their bar for stuff they will accept is surprisingly low. My oldest is now at 'famous' public school and the boys all look terribly scruffy.
Agreed. Indeed, at the Eton-feeder prep school I worked at, there was a certain eye-rolling about anyone who insisted on all new.
How the rich stay rich, lesson 1.
Equally true at state schools ime - mine have all been at very mixed, inner-london state primary and comprehensive schools, and it was invariably the lawyers', medics' and academics' kids who were the ones rocking the bedraggled jumble-sale-left-over, dragged-out-of-a-skip look.
I swear this is a true story: a child from a very deprived, rather troubled family in our inner-city primary once tried to insult my dd3 and her friend (child of a hospital consultant) by saying, "Ner ner, your mum shops at Oxfam". Dd3 and friend were genuinely baffled by this, as much as they would have been if the child had said, "Ner, your mum shops at John Lewis".
