Suits of every shape and size stormed the Fall 2017 runways this season, from Stella McCartney's take on equestrian attire to Jacquemus's translation of the classic le smoking. And naturally, they're slowly trickling on to the red carpet, too. This week, Brie Larson, Allison Williams, and Zoe Kravitz all wore suits, demonstrating three different ways to wear the look—day and night. Larson wore an oversized Alexander McQueen, Williams went plaid in Gabriela Hearst, and Kravitz opted for a classic black Oscar de la Renta tuxedo.

It's shaping up to be the year of power dressing—a trend that began with Giorgio Armani and Donna Karan in the late 1970s and early ’80s, ending today with smart and sustainable suits for the modern working woman. And yes, that includes actresses.

What: The Oscar-winning actress wore an oversized gray double-breasted Alexander McQueen suit with ruffles cascading from its left pocket accented with a classic red lip.

Why: Larson has been on a red carpet role lately, starting with the Oscars and extended by her Kong premiere circuit. She's really demonstrated her range, from edgy gowns that show some cleavage to bright and bold colors. This oversized suit proves that she's a woman who can not only do both—but it all.

What: The Big Little Lies actress wore a classic black Oscar de la Renta suit with a cropped jacket and shimmering gold top.

Why: For their first collection for Oscar de la Renta, designers Laura Kim and Fernando Garcia brought a bit of their Monse red carpet sensibility to the label, mixing de la Renta's classic cuts with a casual, a New York working girl vibe. Kravitz oozes cool in whatever she's wearing, but this look is a nice step up for a formal night at the museum.
