Welcome to your stylish existence, little Kaius Jagger. Rachel Zoe just gave birth to her second son, Kaius, on December 22, and now she’s taking to Twitter to show off the decked-out newborn in his first family photo.

“My incredible family celebrating the birth of baby Kaius Jagger.. #perfectday,” the stylist captions the shot, taken on December 30.

In the photo, we see the one-week old baby in a fancy white ensemble, surrounded by his well-dressed close and extended family, including a straight-faced Rachel, grinning dad Roger Berman, and big bro Skyler, 2. We also spot Rachel’s sister Pam, whom you may recognize from her appearances on the star’s Bravo reality show, The Rachel Zoe Project.

What a gorgeous group! Though we were hoping Rachel might have a little girl to whom she could pass along her immaculate sense of style, we’re glad that SkySky will have a new pal to bond with. Plus, after seeing how well-dressed Rach keeps her first little man, we can imagine the same will be the case for Kaius. When your middle name is a tribute to a legendary rock star — and his style icon ex-wife — you’ve got fashion in your blood!
