Who: Alicia Vikander.

When: Saturday, May 28.

Where: The Louis Vuitton Cruise 2017 presentation, which Vikander attended alongside fellow Nicolas Ghesquière darlings like Jaden Smith.

What: A silk patterned dress and combat-boot heels with contrasting laces, both from the Louis Vuitton Fall 2016 collection.

Why: At his heralded Fall 2016 presentation, Ghesquière sent models down the runway in variations on combat boots combined with his elegant, classically Vuitton designs, and Vikander makes a compelling case for this combination off the runway, too. The dress is a bit offbeat — the floral bears an unshakeable resemblance to one that might be found on linens or curtains, though not necessarily in a bad way, and then there's the matter of the side-cape — and the shoes pick up on that quirk in just the right amount.
