Fashion Winners & Losers! The Best, Worst & Wackiest Dressed At The 2017 SAG Awards

Red carpet alert! Hollywood's hottest stars are showing up in all their glitz and glamour for tonight's Screen Actors' Guild Awards. Click through Radar's gallery to see who won and who lost during the award show's big fashion parade.

Best: Sophia Bush: The Chicago PD beauty stuns in a bright pink strapless Marchesa gown. She set off the look with dangly earrings and wore her hair back in a ponytail.

Wackiest: Michelle Dockery: Lady Mary, we hardly knew ye! The former Downton Abbey star shocked the crowd at the SAG Awards red carpet in an odd, bright striped dress.

Worst: Giulianna Rancic: Las Vegas is missing a showgirl. Rancic looks too shiny in her silver dress that shows plenty of glitz and shoulder. The E! red carpet hostess went with messy hair, too. "I call them beachy waves," Rancic said on camera.

Best: Gwendoline Christie: The Amazonian Game of Thrones warrior calls herself "incredibly lucky" to have had Vivienne Westwood design her black sequined jumpsuit. She chose to go with bright red lipstick instead of a necklace. It's fab.

Worst: Ariel Winter: Va-va voom! Winter dresses like an Oscar at the SAG Awards in bright gold. Her low cut dress shows off her curves but it looks like too much spray tanning and makeup were involved.

Worst: Octavia Spencer: The Hidden Figures actress, who has impressed on the red carpet in the past, looks a little boring in a basic black dress with a sheer front. And her turquoise earrings don't seem to match the gown.

Wackiest: Amy Landecker: It's absolutely Transparent that the actress is out of place in an animal print suit.

Worst: Kaley Cuoco: The Big Bang Theory actress floats down the red carpet in a frothy peachy-pink Marchesa confection that doesn't seem to match her personality. But her co-star Jim Parsons loyally told E!, "Few people have ever looked better."

Best: Samira Wiley: This '50s inspired green print sheath looks so classy on The Walking Dead star. Flawless.

Wackiest: Danielle Brooks: This light-colored pantsuit is blinding on the red carpet and the Orange is the New Black star also accented her Bride of Frankenstein hair with bling. Too much.

Best: Evan Rachel Wood: The actress follows up her tuxedo triumph at the Golden Globes with a gorgeous blue velvet fitted pantsuit by Altuzarra for the SAG awards. "I promised myself I'd wear a suit to every awards show" this season, Wood told E! She adds to her crisp look with simple diamond earrings by Tiffany.

Wackiest: Janelle Monae: The musician appears in both Moonlight and Hidden Figures and is known for following her own style drum. But this time, there are too many cloth pieces stuck everywhere, and even embedded in her Princess Leia double buns! The overdone look overwhelms Monae.

Worst: Sofia Vergara: The Modern Family beauty goes for a different look, changing from her usual big floor-length gown to a knee-length strapless dress which is shiny silver on the top and black on the bottom. "I feel like a ballerina," Vergara said on the red carpet. Sadly, it doesn't seem to be enough dress for the normally va-va-voom sexpot.

Wackiest: Nicole Kidman: Oh, Lion star, hear her roar! Kidman makes a loud statement in a shiny big green gown by Gucci. It's very low cut, continuing the breast bone trend in fashion. Her dress' shoulder work, which includes parrot heads and feathers, would have thrilled Michael Jackson.

Best: Emma Stone: Sometimes the best dresses are the most simple. The La La Land star shows off her glowing skin in an airy, strappy black print dress that is also sheer in spots. The Alexander McQueen gown is just easy peasy and effortless on young beauty Stone.

Best: Viola Davis: The Fences nominee looks like a queen in a white strapless gown with a v-neckline that's perfect fitted to her figure. Davis also dons a big statement diamond necklace with movie star moxie.

Wackiest: Natalie Portman: We hate to pick on a pregnant woman, but Portman takes her retro '60s Jackie style too far here wearing a big white Dior dress with enormous poufy sleeves. Love the dangly fan earrings, though.

Worst: Amy Adams: She makes an Arrival—and it's a letdown. This black low-cut very structured gown appears too stiff on Adams. Just blah.

Best: Julia Louis-Dreyfus: The Veep star looks fresh in a strapless black column dress with a leaf print and stunning gold necklace. It's utterly appropriate woman of a certain age style.

Worst: Taraji P. Henson: The Hidden Figures actress had no plans to hide her girls! Henson lets it all hang out with an overly embellished sparkly ball gown that's so sheer on top it leaves

little to the imagination. A little black bow at her neck points to her chest, too. "People keep stepping on it!" she complained to E! channel. "Get off my train!"

Wackiest: Michelle Williams (right): Is this an edgy fashion risk or a simply a misfire? We think the latter as the delicate Manchester by the Sea star walks the red carpet in a bizarre mixed metal sleeveless long gown. It's silver, pewter and gold, whew.
