I've never seen this trend take off with such ubiquity before — seriously, at least half of the girls were wearing them last night. I like Camilla Belle's (top left) look, as she's a very sultry-looking, tan-skinned Latina who has both the complexion and the eyes to wear such a deep color. Lana del Rey (top right) is a no go for me: her skin, eyes, and brows look gorgeous, but the dark lipstick really emphasizes the odd shape of her mouth. My favorite of these is Kate Bosworth (bottom left). Her natural, almost bare-faced look, with a bit of contouring, black mascara, and groomed brows, is the perfect palette for the lipstick. I'm ambivalent about Amber Valletta's (bottom right) take on it — I think she could have done with less shading on the eyes and a more defined brow for a simpler, cleaner look like Kate's.
