Viola Davis

Viola Davis, a SAG nominee for Outstanding Performance By A Female Actor in A Television Series for "How To Get Away With Murder," has had quite the year on the carpet. From last year's Oscars Awards, in which the actress wore an emerald green asymmetrical Escada ball gown, to the ABC premiere of Davis' hit show, where Davis opted for a black-and-white BCBG cocktail dress, Davis has been one to watch out for on the carpet. Always one for making a statement, Davis gravitates toward bold colors that just glow on the actress. More recently in another Escada number, Davis stunned at last year's Emmy Awards in a sky blue gown that featured short sleeves and a bedazzled bodice. The gown was complemented with chocolate accessories to match the gowns gems for a look that stood out during last year's awards season. Award season kicked off with the 2015 Golden Globes Awards, and Davis looked as regal as ever. As a Best Actress in a TV Drama nominee for "How To Get Away With Murder," Davis walked the carpet with a dress just as luxurious in fashion. The red Donna Karan Atelier gown was strapless and featured crystal embellishments that were right on with this season’s trend. Accompanied by red lips and diamond earrings, Davis brought a touch of old Hollywood to the carpet. It's safe to say that Davis will continue to stun in an equally bold and beautiful look this weekend.

Julianne Moore

Julianne Moore, a SAG nominee for Outstanding Female Actor in a Leading Role for "Still Alice," has always been one to take risks on the red carpet, showcasing some of the runway's up-and-coming fashions and brightest colors. Who could forget that yellow Chrstian Dior dress Moore wore to the Emmys? This year has been no different. Last summer at the Cannes Film Festival, she previewed one of this year's 2015 trends—black and white—with a custom Louis Vuitton by Nicolas Ghesquière oxblood V-neck leather top and belted black-and-white feathered mermaid skirt. Moore paired the look with her signature sleek red hair and a boxy Louis Vuitton clutch. That same week at Cannes, Moore showed up to the carpet with a blush-tone feathered Chanel frock that brought the drama most expect on the red carpet at Cannes. While Moore has been known to rock bold colors, she has also been known to stun in all-black numbers that have popped against her fair skin and red hair. At the London premiere of "The Hunger Games: Mockingjay—Part 1," Moore donned an LBD that was far from simple. The Balenciaga gown featured beaded shoulders and ruched side-detailing that created a sleek look, perfect for the premiere. A fan of feathers, Moore took to this year's Golden Globes carpet wearing an ombre, Givenchy mermaid gown that faded from silver to black, with none other than a feathered bottom. While the look got mixed reviews, Moore's risk-taking has made her a fashion standout that makes her one to watch out for on this year's SAG red carpet.

Julia Roberts

Julia Roberts, a SAG nominee for Female Actor in Television Movie or Miniseries for "The Normal Heart," has been a red-carpet stunner for years. From her first Golden Globes win in 1990 in a Giorgio Armani suit to the Valentino gown, in which Roberts won her Oscar, classic ensembles have always worked for her on the red carpet. Roberts made waves in at the 2014 Golden Globe Awards with a strapless, black Dolce & Gabbana dress. Not one to follow the crowd, Roberts made the dress her own by adding a white collared shirt underneath, creating a sophisticated look that set her gown apart from the rest during last year's award season. While Roberts was absent from this year's Golden Globes carpet, fashionistas everywhere are all the more excited to see just what she wears down 2015's SAG red carpet.

Naomi Watts

Naomi Watts has always been a red carpet stunner. The actress, nominated for a SAG Award for Outstanding Female Actor in a Supporting Role for "St. Vincent," rocked the red carpet for the premiere of the film in a blush sequined Jason Wu dress. The mid-length dress did the talking while Watts opted for simple hair and accessories in the same color family. Watts, also known for donning bold looks on the carpet, wowed this award season at the Golden Globes in a yellow strapless Gucci gown that she paired with a diamond snake-shaped choker. The dress featured minimal, pleated details and a small belt. The gown popped against the carpet and served as a dazzling preview for this Sunday’s show.

Keira Knightley

Keira Knightley, a SAG nominee for Outstanding Female Actor in a Supporting Role for "The Imitation Game," has always been one for whimsical looks on the red carpet, and this year has been no different. At last year's Toronto Film Festival, Knightley rocked the black-and-white trend in the form of a Dolce & Gabbana lace and polkadot dress. The long-sleeved dress flared out at the waist for a chic and girly look that the British beauty kept simple with black heels and minimal jewelry. The same can be said about Knightley's ensemble for this year's Golden Globe Awards. The mom-to-be wore a custom Chanel gown that featured a lace collar with a navy blue ribbon band at the waist, while the rest of the dress showcased a butterfly pattern. We'll be glancing anxiously at the red carpet this weekend to see what fun look Knightley debuts.
