Kim Kardashian, 39, was a gorgeous sight to see when she modeled a pair of gray SKIMS pajamas in one of her Instagram story videos on Aug. 1. The Keeping Up with the Kardashians star was filming herself with her phone while walking up to a mirror in her home and talking to her fans about the night wear choice, which included a loose long-sleeved button-down top and matching loose pants. She also had her long locks down and looked incredible.
