When do people start involving their children in buying their own clothing? DS1 is nearly 4, and I currently get all his clothes on Vinted/eBay/secondhand, or very occasionally in a sale. I don't really want to spend time having him browse through websites looking for things he likes, but if we were buying new I'd be fine taking him to a shop to pick out some things. I've occasionally shown him (secondhand) tops or coats before buying them, just to check that it would be something he likes (he loves very brightly coloured clothing), but I'm not sure at what age that transitions to him picking things out for himself?
I tend to buy clothing in advance for him, so that we're not caught too short in the event of a growth spurt, but I feel a little nervous buying things in size 6-7 when it might be that they're not at all the kind of thing he'll want to wear in a 6 months/a year! (he's very tall, so already in 4-5/5-6 clothes)
