As one half of the four-year old fashion label Holmes & Yang, Jeanne Yang has a knack for creating successful duos. Case in point: twin daughters, Zoey and Sydney. Old souls at heart, the identical almost ten-year olds finish each other’s sentences and, as their mom puts it, are built-in best friends. Rounding out their fantastic foursome is Yang’s husband, Scott—real estate expert by day, stylist to his wife by night (the Hermès headscarf was his idea). When she’s not soaking up family time in her glass-enclosed, Richard Neutra-designed tree house, Yang is traveling the world styling clients like Brad Pitt and Christian Bale. In 2008, after noticing a gap in the fashion market, Yang and longtime client (and friend) Katie Holmes decided to create a high-end line for working moms just like themselves—a uniform of sorts, to simplify women’s lives. Two careers, two kids, a dog, and a lizard named Dragon—it’s all in a day’s work for this energetic powerhouse.
