Rooney Mara In Balenciaga - 'Side Effects' Berlin Film Festival PhotocallBefore her ladylike turn at the ‘Side Effects’ premiere at the Berlin International Film Festival in Germany, Rooney Mara suited up for the film’s photocall on Tuesday.

Donning an ensemble from the Balenciaga Resort 2013 collection, the actress was in a mannish mood.

The pleated, high-waisted silhouette of the wool pinstripe pant, with the wide belt bisecting the torso, is a hard trend to wear. It’s even more challenging when paired with a rigid harness-like top.

But count on Rooney as one of the few who could pull this off with some sense of coolness—despite the bit of awkward bunching that happened at the cuffed sleeves of her white blouse.

She looked relatively identical to the lookbook model, save for the swapping of the boot for a pointy pump and skipping the hoop earrings altogether.

She didn’t really need any accessories, though, as that vermillion lip against her porcelain skin was pop enough.

We can always count on her to wear thought-provoking pieces; perhaps she was paying homage to Nicolas Ghesquière with this look from one of his final collections for the Balenciaga label.
