The Kardashians are one family that you can hardly find one person in the household that can beat his/her chest that they are plastic surgery free. You don't notice the amount of work each family member had because it doesn't strike you until you have seen a before picture of the family just like I was holding my jaw when I saw a before picture of the girls and their mother next to a after picture (pic above)
The plastic surgery is glaring like 7up. Nature isn't that generous, those physical changes I notice in the family must have been altered medically. Check the neck area of their mum in the before and after picture, the falling skin has disappeared in the after picture. To be fair to her though she did mention getting that done on their reality show, Keeping Up With The Kadarshian.
Secondly check out the jaw lines of the girl, the must glaring one is Khloe's, who's my favourite person in the family. lol
