Hanging in Khloé Lewis’ closet is a shimmering lavender party dress with a single puffed sleeve, a bedazzled mini dress with matching cowboy hat, and a rose-colored shirt. She wore these items to Taylor Swift’s Eras Tour, Beyoncé’s Renaissance World Tour, and the Barbie movie, respectively. For Lewis, a 29-year-old PR professional, dressing up made the experience even better.
