Kourtney Kardashian brought the sexiness and shade to her latest Instagram post! The Poosh founder, 41, took to the social media platform on February 19 and modeled her own matching set of fiery red SKIMs. In the mirror selfie, Kourt knelt on the floor of her spacious walk-in closet and showed off the two-piece matching set. Kourt looked super sexy in the snap, sporting a long side braid and a simple pendant necklace for the photo.
