These are all, of course, very different campaigns, though the Dior chain-strap bags each of them are often paired with are similar.
Both actresses are stunning in their ad campaigns, and both have a fresh-faced glow to them that Dior seems to highlight in their ads. But what about the differences?
Mila has a little more of a modern, high-fashion chic, with bold eyeliner and a flawless 'do. Her campaign is full of effortless cool, but her poses are a more interactive, as if she's your hipper best friend.
Our girl J-Law, on the other hand, is on a little more of a pedestal, posed in front of stark backgrounds and rarely looking at the camera. If Mila's your hip best friend, J-Law is a passing angel in a pea coat. (Or little black dress.)
