In an episode that aired back in December, the family decides to have a little fun by dressing up as each other: Kourtney as Kim, Khloé as Kris, Kris as Khloé, and Kendall as Kylie. For Kendall's stint as her billionaire younger sibling, the supermodel throws on one of Kylie's many signature wigs in a pink ombré colour before testing out some of her Kylie Cosmetics lipsticks, even jokingly over-lining her lips the way Kylie used to before getting lip fillers.
