We're Leaving This Week's Best Dressed List to the Pros

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 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 is on a fashion roll! First she matched her costar, 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 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 is ready for Summer! The star was spotted out and about in Hollywood wearing a floral Mary Katrantzou romper.

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.

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 celebrated her Goop Chicago pop-up launch in a feminine black-and-white wrap dress from Atea Oceanie's Fall 2015 collection.

Jamie showed off some skin at the New York screening of Bessie in a sexy pink cutout Cushnie et Ochs dress.

Michelle looked lovely in that purple Tadashi Shoji gown 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.
