Who: Cate Blanchett and Rooney Mara

Where: A photocall for their new movie, “Carol,” at the BFI London Film Festival.

When: Wednesday, October 14th

What: Both stars looked radiant in white, with Blanchett opting for a silk Givenchy Spring 2016 jumpsuit and Mara sporting a ruffled Giambattista Valli Resort 2016 dress.

Why: With matching color schemes and varying silhouettes, Blanchett and Mara prove the “twinsie” look can indeed be done tastefully. Take that, Mary Kate and Ashley.
