Margot Robbie Shows Up To Cara Delevingne's Birthday Party In A Backless Halter Dress And Baggy Pants

This week, the British model and actress's 33rd birthday party was a sight to see for the pop culture world, as she held it at one of Los Angeles' most famous locations, the Chateau Marmont, and had a superstar guest list that seemed to have many top attendees. Cara has been known for having famous friends over the years, being photographed with numerous celebrities, and many of them decided to show up for her special occasion on Tuesday night.

 

Margot Robbie, the famed actress and producer, has reportedly been close friends with the 33-year-old since they acted together in the popular DC film Suicide Squad, so it was no surprise that she showed up to her good pal's party. What grabbed people's attention was the super chic and stylish outfit she wore to it. You can see pictures of her outfit here!

 

The Australian native was photographed arriving at the famous hotel alongside actor Jay Hernandez in a white, ribbed halter dress that was backless, adding some edge to her outfit. She paired the simple yet sultry top with some black, baggy trousers that had silky fabric around her waist. She paired the black and white outfit with some open-toe black heels, and left her famous long, blonde locks down and straightened.

When pictures of Margot were shared on social media platforms like Instagram, fans flooded the comments section with words of praise.

 

"She is killing it in this outfit, my god," commented a fan on Instagram.

 

"She's such a hottie," added another.

 

Others wrote that the actress looked "gorgeous" and "beautiful," clearly happy to see her out and about. One even called her "the baddest girl at the party."
