When we put together our weekly best dressed lists, oftentimes a lesser-known face will pop up in the crowd — an up-and-coming model [1], an actress from a new film, etc. But this week, we've been eyeing the outfits of our favorite A-listers: Reese Witherspoon [2], Scarlett Johansson [3], Gwyneth Paltrow [4], and more stepped out on the red carpet dressed to impress, rocking everything from tight white dresses to low-cut tops. Read on to see how the best of the best won the week and find out what they wore.
Reese Witherspoon
Reese struck a pose at the premiere of her new movie, Hot Pursuit, in a sexy but sophisticated black-and-white dress, which she paired with some t-strap heels.
Scarlett Johansson
Scarlett looked classic as she entered Late Show With David Letterman, rocking a tight white Roland Mouret dress and a trench coat over her shoulders.
Elizabeth Banks
Elizabeth Banks is on a fashion roll! First she matched her costar [5], Rebel Wilson, at the Pitch Perfect 2 photocall, then she wore this Elie Saab dress at a VIP screening of the same film. This design in particular looks lovely on her — we love the belted waist and sheer insert!
Nicole Richie
Nicole kept it sleek and simple at FIT's Future of Fashion Runway Show in a silky white Calvin Klein dress, House of Harlow jewels, and a pair of strappy sandals.
Olivia Munn
Olivia Munn is ready for Summer! The star was spotted out and about in Hollywood wearing a floral Mary Katrantzou romper.
Chrissy Teigen
Chrissy Teigen can pretty much look good in anything, but we're big fans of this wrap-front, tuxedo-inspired white jumpsuit. After all, it's a stylish piece that anyone can pull off [6].
Elizabeth Olsen
Elizabeth looks to be channeling her stylish sisters in this long jacket from their line, The Row, which she paired with skinny black pants and a classic pair of heels.
Gwyneth Paltrow
Gwyneth celebrated her Goop Chicago pop-up launch in a feminine black-and-white wrap dress from Atea Oceanie's Fall 2015 collection.
Jamie Chung
Jamie showed off some skin at the New York screening of Bessie in a sexy pink cutout Cushnie et Ochs dress.
Michelle Obama
Michelle looked lovely in that purple Tadashi Shoji gown [7] at the White House State Dinner, but this printed Thakoon number is perfect for the season. We can't get enough of the first lady's style [8].
