If you thought the 2015 Oscars were a swanky affair, wait 'til you see the show's after-parties.
That's right, stars stripped from their red carpet finest to their next round of designer duds to attend luxe post-Oscars parties, including the annual Vanity Fair bash. While there were many a chic look to choose from, some after-party looks already ranking as our favorite include Lupita Nyong'o (who changed from her pearl-covered Calvin Klein Collection gown to a slim-fitting metallic dress by the brand), Keira Knightley (who went from nude Valentino to the brand's sultry black velvet couture) and Diane Kruger in a punchy red Donna Karan Atelier jumpsuit. Rosie Huntington-Whiteley made a sexy appearance in sequined Alexandre Vauthier, while Naomi Watts slipped into a white hot Giorgio Armani tuxedo.
Stars who didn't make the live ceremony instead attended viewing parties, which is where we spotted singers Miley Cyrus in Schiaparelli Couture and Sia (face fully exposed!) in Marc Jacobs at Elton John's shindig.
The biggest trend story of all the Oscars after-party looks, however, is the nearly naked LBD, which was seen on Lady Gaga (wearing a semi-sheer—though maybe not intentionally so—gown), Irina Shayk (in Atelier Versace), Lily Collins (in Zuhair Murad), Gigi Hadid (in Atelier Versace), Karlie Kloss (in Atelier Versace), Malin Akerman (in Diane von Furstenberg) and Rita Ora (in Donna Karan).
Rita and Irina, particularly, gave us a little more than we bargained for in the body-baring dress race.
