Just one day shy of turning 26, the almost birthday boy made an appearance with momager Kris Jenner at Kardashian Khaos on Saturday.
Like his sissies, Rob made sure to wear his finest designer wear: an abstract Madonna print Givenchy shirt, black pants and sneakers.
Unfortunately for Rob, Kris completely upstaged him in a red peplum dress that was plucked right from Kim's kloset.
Better luck next time, bro.
