We had a minor freakout when we got the news that royal baby number two [1] had arrived. After spending months admiring Kate's flawless pregnancy style [2], we couldn't wait to see her step out for the first time with the new princess, whose name we now know is Charlotte Elizabeth Diana [3]. But the real question on our minds was what would Kate wear? We are fashion editors, after all.

Kate made her postbaby appearance for Prince George [4] in a sweet polka-dot Jenny Packham dress, and her newest big reveal was equally chic. Dressed in an elegant yet fresh floral-printed yellow-and-white dress by the same designer, Kate was all smiles with William by her side. She kept her footwear simple in a pair of nude pumps and her jewelry to a minimum, but her cutest accessory was the newest royal — Her Royal Highness, Princess of Cambridge — who was in a knit white hat and covered in a white blanket. Prince George also dressed up for the occasion earlier [5] in a navy shirt, light blue shorts, and long matching socks. And now that he has a new baby sister by his side, we're hoping for a matching outfit or two in the near future. Read on to see all the latest pictures.

Kate stepped out with Prince William and the new baby, looking lovely in a yellow-and-white floral dress by Jenny Packham.

They made a lovely-looking family. The only thing missing? Prince George, who wore an outfit similar to his father's [6] earlier.

We like that Kate kept it chic and simple, pairing her dress with nude pumps.

Prince William posed alongside the Duchess of Cambridge and his new daughter, Charlotte Elizabeth Diana, in a blue sweater and navy pants.

They kept the little one warm, wrapping her in a knit white blanket.

She's ready for her close-up! We can't wait to see how Kate dresses the new Princess of Cambridge, Charlotte! If George's outfits are any indication, this is going to be one superstylish baby.
