Who: Margot Robbie.

When: Monday, July 4.

Where: A photocall for The Legend of Tarzan in London, England.

What: A black and white Proenza Schouler Fall 2016 dress with coordinating heels, also by Proenza Schouler.

Why: There's not a false note in the look. It's not everyone who can pull off the mid-calf-length silhouette, but combined with a high, shoulder-accentuating neck, it's perfectly proportioned. Her clean, light eyes and rose-tinted lips aren't trying too hard. And what we're really feeling are those shoes — the round, mirrored heel, grommet closure, suede ankle tie, a lot of clashing parts that work into one quirky whole.
