Oh, what we'd do to take a peek in O's closet. The South Korean-born vocalist loves colorful fishnet tights
, leotards, loud prints, metallics and gloves—worn only on one hand, of course. You might even spot her in a neon headdress by costume designer Christian Joy, who has designed pieces for O including a pair of multicolored fringe moccasins. For those of us hesitant to wear headdresses to the office
, we suggest a swipe of O's signature red lipstick.
