Olivia Wilde
We have to hand it to Olivia Wilde—not everybody could pull off this look. But her chill-girl personality and general coolness make this classy-casual ensemble look effortless in the best way. Nodding to the night's host, Wilde wore H&M, pairing a plain tee with a more dramatic, full skirt from the H&M Conscious Exclusive collection. The key was in the styling; even the semi-untucked top added to the overall chicness.
