Yay! xlana guessed the right one!!
I feel like it looks like a "matte" polish. But that's not really indicative of a certain polish since you can buy a matte top coat to convert your polish into a matte finish. I think it could be Essie's Chinchilly? Or Deborah Lippman's Waking Up in Vegas.
It doesn't say in the magazine what her make up is? Or does it only mention her face makeup and not her nail polish?
