Kim Kardashian photoshop and natural.
With Kim, they tend to focus on changing the contour of her body. Her face is already flawless, so they don't need to touch it. Basically, they photoshopped her waist to make it slimmer while leaving the prominence of her butt in tact. Also, they thinned out her upper arm and shoulders. Notice how they make every thinner except for Kim Kardashian's butt and chest.
