After performing "Grateful" from Beyond the Lights during the 87th Annual Academy Awards Sunday, Rita Ora modeled a daring design for the Vanity Fair Oscar Party. Though her black Donna Karan Atelier gown looked relatively demure from the front, once Ora turned around, it was clear that she was going commando. Her booty stole the spotlight, but thankfully, the paneling covered Ora's butt crack. "What we did for Vanity Fair is so cool," her stylist, Jason Rembert, told The Hollywood Reporter. "It's custom!"
Ora thanked Donna Karan for designing the dress via Instagram.
"I just performed at the Oscars!" she tweeted. "Time to party!!!!"
The pop star's third look was her most risqué of the evening. She arrived on the red carpet hours earlier wearing a custom Marchesa dress, Giuseppe Zanotti heels and Lorraine Schwartz jewelry. "I will have a bodyguard following me around and then as soon as it's done, it's like, 'Take my soul away,'" Ora joked to E! News. As far as her dresses were concerned, the "Never Let You Down" singer said, "In the dress world for Rita Ora, there are two things you have to do: what hasn't anybody done [and] what could I do to make myself feel as sexy as possible? I'm really lucky to be in a position where I have an amazing team who can design custom from real incredible designers like Vera Wang and Marchesa and so forth."
For her performance of "Grateful" later that night, the 24-year-old entertainer looked lovely wearing a custom Vera Wang Collection dress, which she paired with Christian Louboutin heels and Bulgari jewels.
Ora wasn't the only star to show some serious skin at Vanity Fair's bash, though.
Sports Illustrated Swimsuit Issue model Irina Shayk also put her bodacious body on display in an Atelier Versace gown and mesh bodysuit. The look came from the label's Spring Summer 2015 collection, and like Ora, Shayk didn't wear underwear. Instead, she relied on paneling to keep her private parts covered.
Are diamonds a girl's best friend, or is double stick tape?
