Sarah Herrington, 33
A poet and yoga teacher, Herrington melded her passions in Om Schooled, her forthcoming book about teaching yoga to children. Her "Zen, minimal" style is channeled in the clean lines of a French-cuffed shirt, linen vest, and vintage bow tie. "This look is straightforward yet idiosyncratic," Herrington says. "Kind of like my writing."
