This Baby Is More Fashionable Than You, Me, Everybody

As someone who has remembered to wear a matching pair of socks about twice in his life, I'm not one to give many opinions on fashion. But I feel like even the most fashionably illiterate among us should be able to call a Kate Spade a Kate Spade when it comes to this super fashionable baby.
I honestly don't know what in The Devil Wears Prada is going on here. Did she pick out those clothes herself? How did she know to color-coordinate like that? How did she learn to take a mirror selfie?
Apparently, the account belongs to @2ah.in, which already has 822k followers. So obviously, this tiny fashionista has found online success before, but now I'm forced to wonder, "Can she use Instagram too?"
