The girl with the low-cut dress: Rooney Mara wows in plunging LBD for Calvin Klein post-show party

She's arguably most well-known for her role as Lisbeth Salander in The Girl With The Dragon Tattoo.
But Rooney Mara couldn't have looked further away from her on-screen alter-ego on Thursday night as she attended a post-show event following the Calvin Klein Collection presentation at New York Fashion Week. 
The 28-year-old actress showed off her feminine figure in a plunging black midi dress as she attended the event, held at Spring Studios in New York.

Rooney toughened up her cowl-neck LBD with a pair of black statement heels as she posed alongside designer Francisco Costa at the party.
The pretty brunette star wore her hair scraped back into a ponytail, with the lengthy locks then sectioned with several bands.
On the make-up front, Rooney opted for a simple but effective grey smokey eye, and added some nude lipstick to her pout.

Rooney's appearance at the event comes after she was named the face of Calvin Klein's Downtown fragrance earlier this year.

Catherine Walsh, Coty Prestige's Senior Vice President, said of the campaign at the time: 'We were thrilled to work with Rooney Mara for this campaign; her individuality and formidable talent resonate with the incredible legacy of women who have been captured in Calvin Klein advertising over the years.'
Earlier in the day, Rooney covered up her dress in a large black coat and wore her brunette hair poker straight as she attended the NYFW show.
