No underwear required! 

The Oscars 2015 were a mostly button-up and conservative affair, but that didn't stop stars including Rita Ora, Gigi Hadid, and Irina Shayk from letting loose in the fashion department for the afterparties. 

After walking the red carpet in a regal blue Marchesa gown and performing in an elegant Vera Wang, Ora set the naked standard in a head-to-toe black sheer Donna Karan Atelier number for the 2015 Vanity Fair Oscar Party. Ora's ensemble left little to the imagination as the singer's backside was only protected by a flimsy piece of black fabric and Giuseppe Zanotti heels. 

Gigi Hadid and Irina Shayk - Vanity Fair Oscar Party

After a few dress changes throughout the night, Hadid carried on with the trend at the Vanity Fair 2015 afterparty in a black Atelier Versace dress with peekaboo panels, which also revealed her cleavage. The stunning number also featured a waist-high slit, which Hadid, 19, teamed with black and gold sandals. 

 

Skin was in, as Sports Illustrated swimsuit model Shayk picked up the baton in a black Atelier Versace gown with a sheer side that was covered in sparkly jewel embellishments. The newly single model, 29, commanded attention in the feisty number as she had no choice but to skip out on wearing underwear. 

Heidi Klum - Elton John Oscar party

 

Opting out of the noir theme of the night was supermodel Heidi Klum. The Project Runway star, 41, shined in a silver sparkle gown that was slashed with sheer paneling all over for Elton John's 2015 Oscars afterparty.
