America’s best family of self-promoters has moved beyond justwearing each other’s designs, orwearing each other’s tour merchandise. Now, they’re simply wearing each other’s faces. Yesterday, Kourtney Kardashian was seen performing carpool duty while wearing a T-shirt screen-printed with a picture of a windswept Kendall Jenner riding a horse. She paired the family-friendly shirt, from Kendall and Kylie’s limited-edition collection of “selfie tees” for PacSun, with a pair of distressed jeans for a just-really-casual look.
