There's a brief moment when organizing your makeup collection and the idea comes in that's strikingly similar to your Barbie playdates as a kid. Hmm Dior, why don't you come over and say hi to NYX? Oftentimes, product BFFs come together in beautiful-but-unexpected scenarios—take the rough lip, for example.

Perhaps the best love story between high and low products is the one between Maybelline and Chanel. Samira Nasr explains how mascaras from the two brands got together in her makeup bag: “I’m mascara- obsessed, and constantly looking for the perfect one that will give me a thick, clumpy lash that’s not too clumpy' the fashion director at Elle told us in her Top Shelf. “I love Chanel Le Volume de Chanel followed by Maybelline Great Lash Lots of Lashes, because the Maybelline wand will clean up the Chanel clumps without taking the mascara off. I figured that out myself. [Laughs] But I've really tried every mascara from drugstore to Dior.”
