And while we'll be there style-stalking in person, the celebrity-designer pairings that we've already been tipped off to are just too good to keep to ourselves!
First off, to go with the Americana theme of the night, stateside designers will have a huge presence.
As we previously reported, the third co-chair of the night, Patrick Robinson of The Gap, has teamed up with a bevy of emerging American designers to dress eight stars: Kirsten Dunst and Jamie Bochert (who will both wear Rodarte for Gap), Riley Keough and Kerry Washington (who will both wear Thakoon for Gap), Jessica Alba and Vera Farmiga (who will both wear Sophie Theallet for Gap) and M.I.A. and Zoe Kravitz (who will wear Alexander Wang for Gap gowns).
Then we'll see democratic designer Tommy Hilfiger dressing Mad Men's curvy siren Christina Hendricks, Zoe Kazan and a bunch of guys including Jimmy Fallon, Peter Som and Mick Jagger, while Michael Kors has created gowns for lovely American beauties Brooke Shields, Diane Lane, Carolyn Murphy and Chanel Iman, as well as model Natasha Poly.
Expect to see new CoverGirl Taylor Swift, along with power couple Jessica Biel and Justin Timberlake, donning American master Ralph Lauren, and Diana Kruger wearing a sleek Francisco Costa design for Calvin Klein.
The Queen of New York, Donna Karan, will dress teen model Karlie Kloss and Meryl Streep's daughter Mamie Gummer, in her sculptural pre-fall wonders, while Project Runway winner Christian Siriano has the honor of dressing Melania Trump and Kenneth Cole will outfit Emmy Rossum.
CFDA president Diane von Furstenberg will dress the newly engaged Kristen Bell in a ruffled chiffon gown (could her wedding dress be next?) and Gwen Stefani will wear her own silver lame L.A.M.B. creation, inspired by a slinky 1930s gown.
Surprisingly enough, Wintour, one of the most important women of the night (although, she's not an American Woman, per se), will be wearing couture from the French house Chanel, as will Twilight star Kristen Stewart.
And as for the other non-American designers, Burberry's Christopher Bailey will represent the U.K. by dressing a stable of guests, including Emma Watson, Claire Danes and British Victoria's Secret model Rosie Huntington Whiteley, while fellow Brit Stella McCartney will design eco-friendly gowns for friends Liv Tyler and Kate Hudson.
Italian design will stand tall with Lady Gaga donning Prada, Versace styling Gisele (once again) and Ivanka Trump, design duo Dolce & Gabbana dressing Naomi Campbell and Eva Mendes in sexy black gowns and Valentino glamming up Anne Hathaway and Kate Bosworth.
Representing France, Stefano Pilati from YSL will clothe the bodacious Mad Men star January Jones and Giambattista Valli is designing for Rosario Dawson.
