Rachel Zoe has built her career around helping people look and feel their most stylish. In fact, the fashion guru is one who helped define early to mid-aughts celebrity style - think Nicole Richie and her oversize sunglasses, long, layered necklaces, and flowy boho 'fits, and Lindsay Lohan's ludicrously capacious bag era. The designer is also a disciple of the idea that looking and feeling good extends beyond what you wear.
