Golden Globes 2019: Best Dressed Stars

As expected, the pop star-turned-actress owned the red carpet, delivering all the glamour in a voluminous periwinkle blue Valentino couture gown, custom Giuseppe Zanotti boots and dripping in over 100 carats of Tiffany & Co. diamonds. Gaga, who is nominated for Best Actress in a Motion Picture -- Drama for her performance in A Star Is Born, already took home the award for Best Original Song for the film's hit, "Shallow."

The supermodel was show-stopping in a gold Atelier Versace gown that featured a sexy, thigh-high slit, but her best accessory of all was her partner, Bradley Cooper, who is nominated for Best Actor and Director for A Star Is Born. Cooper was as handsome as ever in a custom white Gucci suit and black bow tie. 

Wowing in white! The evening's co-host won Best Actress in a Television Series -- Drama for her performance in Killing Eve. She stunned on the red carpet in a draped white Atelier Versace gown, completed by a waved bob for an elegant Old Hollywood result. 

The winner of Best Supporting Actress in a Motion Picture -- Drama for If Beale Street Could Talk radiated in a custom pink sequined Alberta Ferretti number, Messika jewelry and Vince Camuto shoes, topped off with a chic angled lob. 

Although she didn't win tonight, the GLOW actress won our hearts by giving us the ultimate princess moment. Her frothy, light blue Vera Wang gown instantly made our jaws drop. We also love the reveal of an embellished bralette for a slightly sexy twist. 

The Riverdale star elicited a double take as she matched the red carpet in a brilliant Khyeli Couture gown. She finished off the ensemble with slicked-back tresses, Swarovski earrings and, wait for it, matching eyeshadow!

Keep the princess vibes coming! The Shameless star continued the ball gown trend in petal pink, a creation by Monique Lhuillier, who dressed a plethora of stars on the red carpet Sunday evening. 

The British beauty ditched her whimsical Mary Poppins-esque style streak for the Golden Globes by turning out this unexpected, edgy and intricate dress from Alexander McQueen. 

Gorgeous in green! The Luther actor had jaws dropping when he arrived to the red carpet in this sexy creation from Ozwald Boateng.

The Good Place leading lady looked straight out of a storybook in a blush-colored, pleated Zuhair Murad dress. The sleeveless gown featured a deep-V neckline, empire waist and crisscross straps in the back. Bell accessorized the whimsical look with a gorgeous diamond bracelet and equally stunning diamond rings.

The Crazy Rich Asians star was breathtaking in a bespoke tulle Vera Wang Collection gown, with a sheer classic corset bodice, accented with a rouille orange velvet ribbon. She paired the ensemble with Giuseppe Zanotti shoes and Messika jewels. 

Switching it up! The Best Actress in a Drama TV Series nominee kept it classy and unique in a Stella McCartney custom silk tulle one-shoulder dress with pleated skirt and rose crystal detailing. She took the look to another level by wearing it with black skinny tuxedo trousers and Chopard jewels.

The Favourite star exuded elegance in a custom-made, long-sleeve, blush embroidered Louis Vuitton creation. Stone accessorized her look with LV sandals, clutch, earrings and rings from the Louis Vuitton High Jewelry Collection. 

Looking sharp! The Golden Globe nominee stood out from the crowd, opting for custom Louis Vuitton look that included an embroidered bib, black shirt, pants and boots, finished off with Cartier accessories. 

The Americans star looked spectacular in a shimmering silver sequin Monique Lhuillier frock that featured a sexy draped V-neckline.

The Crazy Rich Asians star did not disappoint! Looking absolutely ravishing, Chan was breathtaking in a navy Valentino creation. The billowing look featured a high neck with a dramatic skirt over what appeared to be shorts.

J'adore Theron! The blonde bombshell was the epitome of sophistication in a black-and-white Dior Haute Couture number that featured a sexy cutout in the bodice and big bow around the neck. Theron kept the rest of her look simple, only adding diamond jewelry by Bulgari to complete the ensemble.

For a second consecutive year, the actress opted for a Ralph & Russo design. The pearlescent floral ball gown featured a silk, velvet halter neck bow and Chantilly lace overlay embellished with scattered metallic gold crystals. For jewels, Cruz rocked Atelier Swarovski. 

Two-time winner! The brunette beauty won for the second time in a row for her performance as Mrs. Maisel and she was marvelous indeed in a bright yellow Prada gown. 

The American Horror Story actor ditched a suit for a sheer black shirt, trousers and Maison Margiela's iconic split-toe hoof-like Tabi boots, which seemingly plays up his satanic character in Apocalypse.

The Black Panther leading man may have skipped the red carpet, but the wait was worth it because his silvery custom Atelier Versace suit, boasting a beautiful hand-embroidered and beaded evening jacket, gave us life. The stud flawlessly finished the ensemble with glittery Christian Louboutin loafers and Tiffany & Co. jewels. 

We can always count on Nyong'o for a major red carpet moment. The Black Panther actress was a vision in an electric blue, chain fringed custom Calvin Klein gown, Bulgari jewelry and Aldo shoes. 

The Irish beauty was a Gucci gal in a custom antique platinum beaded, crystal-embroidered plunging gown. Ronan amped up the glamour with Chopard diamond-and-emerald chandelier earrings.
