Rooney Mara Wears A Crazy Cool Sweatshirt At Sundance

Holy crap, this sweater is amazeballs!
Rooney Mara kept it deceptively casual at the premiere of The One I Love during the Sundance Film Festival yesterday.
From afar, the actress looked like she was wearing your typical, boring all-black outfit, but upon closer inspection, we noticed the voluminous basketweave sleeves of her Balenciaga sweatshirt!
COOLNESS!
We love it! And we don’t even hate Rooney’s messy updo!
We’ll never look at a sweatshirt the same way again!
