Rooney Mara's love for black and white scaled new heights at the Cannes Film Festival over the weekend.
On Saturday, the actress attended the Ain't Them Saints Bodies premiere in a contrast Christian Dior dress with flutter layer over the bodice and draped skirt.
It looked fab on the runway, but swamped Rooney's petite figure in this case.
Sunday, the 27-year-old walked the red carpet at the For the Love of Cinema event in another two-toned Vera Wang dress, which featured a leather panel at the bust.
The same Brian Atwood heels and severe bun completed both outfits.
Guess we can't expect Roons to venture out of her comfort zone anytime soon.
Oh, well.

Can fabulous cheekbones and an insouciant attitude help sell perfume?
The peeps at Calvin Klein are banking on it as they've cast the broody Rooney Mara in their latest ad campaign for new scent Downtown.
The actress wears a leather jacket and leans back against a red-brick wall in the first released ad (above) shot by Jean-Baptiste Mondino.
The fragrance itself, which boasts notes of Tunisian neroli, green pear and watery plum, will be available in stores nationwide in September.
Sounds YUMZ!
In addition to the ad campaign, Roons will star in a commercial for the perfume directed by David Fincher, who directed the actress in The Social Network and The Girl With The Dragon Tattoo.
That's a lot of talent in one commercial! It better be damn good!

Are you surprised to see Rooney Mara at a Calvin Klein event? Ha!
The actress bit back her smile while walking the black carpet at the IFP, Calvin Klein Collection, and Euphoria Calvin Klein Women in Film celebration at Cannes on Thursday night.
The VAST majority of Rooney's past looks have been either black or white, or, in some cases, both, but this time we got to see her change it up ever so slightly.
She went nude!
Roons chose a delicate slip of a dress by the designer for the event, styling it with t-strap heels and tight bun.
Though pretty and ethereal, it's also rather forgettable.
We hope she wears something a bit more exciting next time!

What the punk?! Rooney Mara isn't wearing black!
We can hardly believe our eyes!
The actress and co-chair along with Riccardo Tisci predictably wore Givenchy to the Met Gala, but her ruffled, lacy gown screams more bridal than punk.
Maybe if she'd taken a pocket knife and slashed it up a little, it'd be more hardcore.
As it stands now, it just makes us think of lace doilies.
Rooney's severely pulled back hairdo and purple lips had a punky vibe, but since she always has that same hair and makeup look, we're not sure if it was part of the theme or not.
Not loving it!
Are U???

Is it too soon to call this Beyonce's best year ever???
Sure, it's only April, but she's already dominating in SO MANY WAYS!
And now the singer has been named an honorary chair at this year's Met Gala, which will take place on May 6!
Bey joins co-chairs Rooney Mara, Riccardo Tisci, Anna Wintour, and Lauren Santo Domingo, and may have some surprises in store for us, though nothing has been officially confirmed.
And we really hope she embraces this year's unorthodox punk theme.
Can you imagine the ultra glam Bey in a punk-y gown?! Now THAT should be very, very inneresting!
Let's fast forward through this month, shall we???

Rooney Mara has been busy feeling the Side Effects on her promotional tour, so it is nice she has the time now for some much-needed rest and relaxation.
The stylish actress traded in her designer duds for some casual garb for a romantic lunch with her boytoy, Charlie McDowell, on Wednesday in Los Angeles.
The couple are still going strong after three years together and co-parenting two dogs.
They make such an adorably indie couple! We're so happy you took him out in public to play, Rooney!
We bet Charlie would look EVEN BETTER in a suit. Maybe you should bring him to your next movie premiere?!

Interview magazine is really reelin' them in!
Heidi Klum joins Rooney Mara and Cameron Diaz as a March cover girl for the mag, snagging the front of the German issue.
The supermodel looks seksi and svelte in a face-print Jeremy Scott for Adidas swimsuit, previously worn by Rita Ora, and fishnet tights.
The 80s homage is complete with green and fuchsia eye makeup and big, bouncy waves.
We don't know about you, but we're getting some serious Olivia Newton-John vibes.
Let's get physical! Ha!
