We're Stealing Your Look for This Weekend, Sienna Miller

Sienna Miller never fails to turn out effortlessly chic outfits we're eager to copy, and her latest night-out ensemble is no exception. The actress stepped out in London wearing an ankle-grazing slip dress, proving a black gown can be made summer-ready with a few styling tricks.

They key? Select a lightweight, silky fabric that comfortably skims the body (no body-con silhouettes here) and pair it with strappy, barely there sandals. For an It-Brit spin, add a skinny scarf à la Sienna in lieu of a necklace—the effect is at once polished and a little rock 'n' roll. Be right back—we're off to re-create this look for our Friday night on the town.
