If you have the money, then why not. Mine was 2200 in 2006. Plus additional shoes, bag, professional makeup, hair, limo, all the shebang. Wealthy parent. It was fun and I wouldn't change anything and neither would my dad. It was certainly not a lot of money for him.
I hate this 'oh, but you can find it cheaper, even cheaper, the cheapest, just scrounge it from the bin'. One thing is when you can't afford it. But if you can - then why not? Surely that can be adapted to adults to, not just teens. What's your 'thing'? Bags, jewellery, clothing, cars, holidays, city breaks, books, gigs, theatre, fancy food, skincare, horses, other hobbies/experiences/stuff? Just do them on the cheap, or don't do it at all? So instead Maldives stay in a hostel in Scunthorpe?
Going into debt or spending way above your means is silly, of course. But if you can afford it - go for it, don't skimp, don't be a miser, it's your kid. It's a once in the life occasion.
