Don’t mistake me for a hater –– I’m a big fan of the concept of Fashion for All. But lately I can’t help but shake a nagging annoyance for the budding crop of prepubescent fashionistas I see all over the place. Youngsters in Hollywood swathed in designer gowns or super-savvy tween bloggers sitting shoulder-to-shoulder with Wintour and Lagerfeld at Fashion Week? It’s exhausting, and kind of scary. There’s a way to be young and stylish while still being young –– and that avenue is more Limited Too, in my opinion, than unlimited Moschino and too much Yves Saint Laurent. Am I right, or am I just getting bitter in my old age of 21?

Consider Tavi Gevinson, a.k.a. The Style Rookie, a 13-year-old blogger who’s no more a rookie than, say, Agyness Deyn or Andre Leon Talley. She’s probably not even lost her last baby tooth yet, but already she’s meandering all around the globe for fashion week, doing guest columns for Vogue, and producing quotables along the line of, “People don’t know if I’m 13 or 80, and, sometimes, neither do I.”

Doesn’t it kind of creep you out in a Baby’s Day Out sort of way? Like, who’s taking care of this girl? If Tavi’s already mastered the art of granny dressing, haute couture-schmoozing and, worst of all, flashing really jaded half-smiles at the paparazzi, what’s going to happen when she finally hits her Sweet Sixteen? Will she be a nuclear physicist by then? Will she own her own country? And will that country accept nothing less than than the latest in Armani Privé for their uniforms?

And then there’s Hollywood starlets getting all creepy couture on us. Like, Dakota Fanning –– when did she turn 30? And remember previous Abigail Breslin, playing wide-eyed Olive in Little Miss Sunshine, looking fresh out of her tea-party-with-stuffed-animals phase? Now she’s doing Jenny Humphrey-goes-bad eyeliner and leaning against SCARY BRICK WALLS for Nylon magazine.

I don’t know –– I’m half jealous that they get to wear labels they can barely pronounce, and half disappointed that fashion has come to this. It sort of devalues it all, doesn’t it? What do we, the 20somethings and beyond, have to look forward to now, when our fashion peaks should’ve been, according to young Hollywood, like six years ago?

Of course, the fact that little Tavi owns the coveted Miu Miu naked girl collar and I don’t doesn’t exactly sweeten the deal.
