Are the Hadid Sisters Fashion's Fiercest Siblings?

You can thank Balmain for pitting some of the coolest sisters in the fashion world against each other. The brand's latest ads feature some very fierce sister pairings: Gigi and Bella Hadid; Kendall and Kyle Jenner; as well as Joan and Erika Smalls. The ads were shot by Mario Sorrenti and include all the ladies looking all kinds of cool in their couture.

While it's hard to not look away from all that camera mugging and those beautiful clothes, the ads did have us wondering which sister pairing really slayed the Balmain fall/winter 2015 campaign. Take our poll and weigh in for yourself!
