As long as we've known Kim Kardashian West, we've known her trademark beauty look: brunette hair, perfectly arched eyebrows, and — of course — contoured cheekbones.
These attributes have been a key part of the KKW Beauty founder's aesthetic, and while her go-to beauty choices work, she doesn't shy away from mixing it up.
