Forever Young - the rise of the haute kidult

It has been said I have the taste of a nine-year-old. This isn't an insult, it's a fairly good summary of me. The good thing is in my new life in a senior role at a magazine for tweenage girls, I am free at last to unabashedly love the cute stuff - to decorate my desk with Hello Kitty without restraint, to add Blythe dolls and Littlest Pet Shop without shame.

It's also carte blanche to reverse age - to choose childlike things which I've always liked best.

That's not to say it's time to plaster myself with cheap diamantes from Diva (not saying I have anything against Diva, or diamantes, or plastering myself with things). It's more about the somewhat slicker stuff, and I'm not the only one.

There must be huge numbers of people like me - haute kidults, that is, solvent adults with a taste for high-end kiddy kitsch complete with price tag to set it out of reach of bona fide kids except Suri Cruise. How else to explain the popularity of Mawi x Disney Couture, the existence of implausible diamond Hello Kitty jewellery, and the fact the Tokidoki x Karl Lagerfeld figurine (plastic!) costs nearly AU$200? Lagerfeld himself must be young on the inside - he gave his cat, Choupette, an iPad, which sounds like something a child would do.

I am 27 years old. When faced with a big, square and sensible Mulberry Bayswater in thick black leather, I inevitably reached for a raspberry mini Alexa, a handbag so weeny it cannot fit my diary. It occurred to me the Bays was the better investment - the sort of bag that could see me through to age 90 and then some. It also occurred to me that something so practical could make me feel like I was age 90. No, far better to go for a bubblegum-pink shrunken It Bag, one that I lovingly pet as if it were a teacup Yorkie. This is after vetoing a mint green Mulberry with flower clasp - that I feel really IS like a child's bag, that looks like something out of Forever New on a good day. It is so little I have grave fears more than an iPhone could be tucked inside and its discount price tag was still the princely sum of more than AU$400.

Fun fashion is ageless, I think. I never believed in those 'How to dress for your age' articles anyway. Let me wear my cartoon cats and fluffy ears beanies (no matter how much Guardian writer Hadley Freeman decries them). Let me be a haute kidult - I found the fountain of youth and it looks at once cheerful and eye-wateringly expensive.
