All of the Kardashian/Jenner kids inherited the best from their parents. Kim, Kourtney and Robert have the exotic Armenian look from their father, but with Kris' softer features, Khloe is tall like her mom, Kendall and Kylie, while not really exotic, are pretty cute girls. They all got lucky in the gene department!
Even Kris's mom, MJ, looks good for her age...Always dressed so nice and she's really skinny/tall.
Kim's grandfather from her father's side was soo handsome. They get their cheekbones and big lips from him:
