Several celebs turned to the tried-and-true hue, reminding us all that a black dress doesn't have to be basic or boring. Left to right: Alicia Vikander in Louis Vuitton, Kirsten Dunst in Dior Couture, Salma Hayek in Alexander McQueen

Not quite nude, but not quite blush, this frothy neutral hue ranged from balletic and feminine to straight up sexy. Left to right: Chrissy Teigen in Zuhair Murad, Nicole Kidman in Armani Prive, Felicity Jones in Dior

Lace shed its sweet, girlish reputation for the night, taking on a new level of drama with va-va-voom volume, lingerie details and eye-catching appliques. Left to right: Cynthia Erivo in Paolo Sebastian, Ava Duvernay in Ashi Studio, Georgina Chapman in Marchesa

Tiered and tinseled fringe details brought a glamourous flapper flair to Hollywood's biggest night. Left to right: Olivia Culpo in Marchesa, Halle Berry in Versace, Emma Stone in Givenchy Couture

The key to a standout red carpet dress? Details that don't fall flat. Floral appliques, floaty feathers and beaded embellishment brought these looks to life. Left to right: Hailee Steinfled in Ralph & Russo, Janelle Monae in Ellie Saab, Octavia Spencer in Marchesa

A few daring divas eschewed the 'don't wear red on the red carpet' rule, proving it entirely false with their stunning scarlet looks. Left to right: Viola Davis in Armani Prive, Ruth Negga in Valentino, Ginnifer Goodwin in Zuhair Murad

High slits and peekaboo panels took everyone's favourite '90s trend to ultra-sultry territory. Left to right: Brie Larson in Oscar De La Renta, Busy Philipps in Elizabeth Kennedy, Taraji P. Henson in Alberta Ferretti

Playing foil to the golden girls above, some stars shot the moon in shimmering sterling and platinum tones. Left to right: Priyanka Chopra in Ralph & Russo, Sofia Boutella in Chanel, Teresa Palmer in Prada

Metallics in general had a major moment, but the ladies in gold set the standard. Left to right: Charlize Theron in Dior Couture, Jessica Biel in Kaufman Franco, Dakota Johnson in Gucci.
