2020 Screen Actors Guild Awards: Best Dressed

J.Lo did not come to play! The Hustlers star stunned in a sumptuous, off-the-shoulder black gown by Georges Hobeika that featured a bow leading to a long train that glided elegantly behind her. She completed her screen siren sartorial story with over $9 million in Harry Winston diamonds and Casadei heels. Lopez's luxurious jewels consisted of a cascading diamond drop necklace, diamond drop earrings, a wire diamond bracelet, a secret cluster diamond bracelet, a cushion-cut diamond ring and lotus cluster diamond ring, all set in platinum. Keeping the focus on her accessories, she kept the rest of her look simple, pulling her brunette locks back into a chic bun.

The Marriage Story star showed off her curves in a teal, luminous silk custom Armani Privé gown that featured a plunging neckline, draped pleating at the hips and an open back accented by crystal embroidery along the straps. A bold red lip added to her vixen vibes.

The Harriet star made a case for voluminous fabrics with her bright red-and-neon pink custom Schiaparelli Couture number, complete with diamond jewels by Roberto Coin.

Talk about a silver steak! The Queen America star sparkled in a metallic Julien X Gabriela dress and matching Giuseppe Zanotti sandals and chandelier earrings.

Men can wear pastels, too! The Stanger Things star may be young, but he was the best-dressed guy on the carpet in this satin, baby blue Balmain suit, complete with a pleated cummerbund and the signature buttons the fashion house is known for. A white button-down and sneakers helped anchor the look and keep it looking young and fresh.

Hello, neon queen! The Game of Thrones gal was pretty in bright pink in this belted, strapless Louis Vuitton number and matching but slightly paler lip. Turner kept the look playful by wearing her bleach blonde locks down and straight.

Is she not the cutest? The Once Upon a Time... In Hollywood actress wore one of the night's biggest trends: a notice-me suit. Butters' jacket-and-cropped pants pick by Dsquared2 brought the drama thanks to its silver shine and black lapels, and her star-adorned tie, white button-up and black-and-PVC ankle pumps by Chinese Laundry only added to the sassy style, as did her side braid and tiny black Dan Life bag.

The Big Little Lies actress' billowy Valentino dress featured a tangerine hue, plunging neckline and exaggerated butterfly sleeves.

Hot mama! The blonde beauty looked ready to party in a chic black polka dot CELINE by Hedi Slimane dress with a chain-inspired single shoulder element. She added even more sparkles with plenty of Harry Winston jewelry and black-and-silver peep-toe heels. Witherspoon finished her look with a deep side part in her sleek bob, a red lip and a black clutch.

The Morning Show star slipped into a vintage, off-white silk satin gown by John Galliano for Dior, purchased at LILY et Cie in Beverly Hills. 

The Bombshell star looked amazing in a custom crystal-infused silver crop top and black, belted maxi skirt by Givenchy. To top it all off, she even wore a platinum-and-diamond Tiffany & Co. bracelet as a hairpiece! 

The pregnant SAG Award winner glowed in an off-the-shoulder, custom black silk gown by Louis Vuitton that she added a bit of razzle-dazzle to with a diamond feather brooch and ring set in 18K white gold, both by Forevermark, and a scarlet lip.

Just go ahead and give the Stranger Things star a gold medal for this in an exquisite long-sleeved, full-length Saint Laurent by Anthony Vaccarello metallic gown paired with Cartier jewelry.

The Perfection star looked like, well, perfection in this romantic, ruffled pale pink Jason Wu confection, brown diamond Pomelatto jewelry and silver Ruthie Davis platform heels.

He's electric! The Stranger Things actor brightened up the carpet in this blue suit that had a black-and-white patterned slit at the bottom of the pants for some extra oomph. A black turtleneck and matching dress shoes grounded the bold hue.

Va-va-voom! The Game of Thrones alum went for major volume in this bow-adorned floral Miu Miu gown, which she made the sole focus by wairing her curls up in a high bun with just a few tendrils peeking out. 

The Stranger Things star hit the red carpet looking as elegant as ever in a winter white cape-and-pants ensemble by Louis Vuitton. Brown complemented the classy couture look with a thin diamond necklace and ring by Cartier, diamond studs, a smoky eye and dusty pink lip gloss, and she wore her hair sleek and straightened.

We think Betty would approve of this dreamy black-and-white tiered Miu Miu dress lined with pearls along the chest and paired with Harry Winston jewels.

The Game of Thrones star looked quite dapper in a maroon-and-black, silk-and-wool jacquard brushstroke-print jacket, black trousers, black tuxedo shirt and oxford shoes, all by in Ermenegildo Zegna XXX.

The Big Little Lies star went for a bit of shimmer in a subtly sparkly, custom navy blue Michael Kors Collection double crepe sablé gown with a thigh-high slit accented with ruffled detailing. The real shine was in her bold gem jewelry and heels, though.

The Riverdale star opted for a romantic look in a subtly sparkly, nude-hued number with off-the-shoulder, chiffon sleeves and a plunging neckline.

The Handmaid's Tale actress appeared to be inspired by the ocean in this flirty, tiered turquoise Monique Lhuillier dress, which she paired with loose waves and a bright red lip.

For his gig presenting at the awards show, the Rocketman star opted for a Brunello Cucinelli ensemble consisting of a gray velvet tuxedo jacket with shawl lapels, matching tuxedo trousers, classic white shirting and a black bow tie.

The Act star opted for the naked dress trend, looking sophisticated in a semi-sheer black, lingerie-inspired corset dress by Jason Wu and slicked-back hair.

The Native Son actress suited up in sparkly black Chanel separates united by a giant floral pearl brooch.

The High Fidelity star looked incredibly sophisticated in a bow-adorned, custom peach Oscar de la Renta gown paired white evening gloves. 

The Handmaid's Tale star covered up in a pretty pink-and-red, long-sleeved Monique Lhuillier dress, which she amped up with a matching ruby clutch and lip.

At the SAG Awards to support both her boyfriend, David Harbour -- who was nominated with his Stranger Things ensemble and stood by her side on the carpet -- and her brother, Game of Thrones star Alfie Allen, the "Hard Out Here" singer looked like picking out an outfit was easy! She gave off Valentine's Day vibes in a whimsical, bright pink-and-red dress with a plunging neckline and rose-inspired detailing at the hip. 

We're sure Gurira made Wakanda proud in this red hot, fitted dress and rainbow-hued gem statement necklace.

The Once Upon a Time... In Hollywood star was plaid perfection in this tiered Chanel dress paired with a chain belt, silver sandals and layers of gold chains.
