Kate Young was named the most powerful stylist in Hollywood, but in her tight-knit Brooklyn neighborhood she’s better known as Stellan and Leif’s mom. After seven years at Vogue, where she started out as Anna Wintour’s assistant, Young branched out on her own and the rest, as they say, is history. The past month alone has been a veritable whirlwind—from styling Jason’s Wu’s highly anticipated fall 2012 runway show to dressing her clients (and friends) Natalie Portman and Michelle Williams for the Oscars. Young’s own edgy-meets-classic wardrobe and artfully crafted home achieve that hard-to-come-by combination of effortless and chic. Same goes for the eclectic pieces scattered around her boys’ shared bedroom—from animal costumes and wood guitars to the impossibly-cool tweed teddy bear given to her older son as a birth gift by the house of Chanel.Stellan, four, and Leif, twenty-months, March 2012
