We all know Kim Kardashian shades (aka contours) her face (she even showed us the whole process!), but is she shading her lips now, too? Take a look here:
It's looks a bit like she's got a slightly darker beige shade on the sides of her mouth. Maybe her makeup artist was just a little heavy with the lipliner that day (and I'm assuming he/she used the two-ended lipstick/liner product in the Khroma Beauty Nude Lip Set in Au Naturel—it looks exactly like this shade), but there's so much of the darker color that I'm thinking it was intentional. And that leads me to believe the deeper hue is meant to make her lips look poutier and more bee-stung.
An interesting idea, don't you think? I'm kinda curious to try it. Are you?
