Elizabeth Olsen

Plus, a very, very good beauty look.

The celebrity-filled red (uh, purple) carpet featured dozens of dazzling looks — and some genius Marvel-inspired accessories.

Olivia Wilde looked damn good on the same red carpet, too.

The video was filmed on location in Buenos Aires.

Just because you've never heard of Serinda Swan doesn't mean she can't ace a Proenza Schouler look.

Ok, it was mostly just Aubrey Plaza and Elizabeth Olsen who did that, but we're here for it.

Her red carpet look was Very Good.

And two One Direction-ers get in on the fashion scene wearing blue.

Not counting the Met Gala attendees.

Marie Kondo, Sarah Paulson and Caitlyn Jenner shined in distinct ways.

And her makeup was on point, too.

Keira Knightley, Taraji P. Henson, Naomi Campbell and Jessica Alba prove that fashion really can make you happy.

Spring wardrobe inspiration, right this way.

The youngest Olsen wore Saint Laurent to the London premiere of "Avengers: Age of Ultron" on Tuesday.

Gwyneth Paltrow, Dakota Fanning and more have us thinking dark colors are the most chic (and practical) way to get through the season.

In a maxi skirt. She is an Olsen, after all.
