Kendall and Kylie Jenner for Balmain Fall/Winter 2015 Campaign

It’s all about hot sisters for the fall/winter 2015 Balmain campaign.

Kendall and Kylie Jenner have moved on up from posing together for PacSun and TopShop. The sisters are now pairing up for Olivier Rousteing’s upcoming portfolio of high-fashion couture.

After last season’s men’s campaign featuring Kim Kardashian and Kanye West, Rousteing felt it was only appropriate to continue the progression of unconditional love for fall/winter 2015.

“Starting with a determination to once again focus on the beauty of an intimate connection, my team and I quickly concluded that a celebration of the unique and unconditional love of siblings is a natural progression from the spirit of last season,” Rousteing expressed.

And the Jenners aren’t the only sisters involved. Gigi and Bella Hadid have also joined forces for the project, which the brand is appropriately titling the “Sister Act.”

We’ll also being seeing Joan Smalls and her gorgeous sis Erika Smalls in this Balmain project.

Creative Director Mario Sorrenti noted, “Watching [sisters] work together also made clear to me the universality of an age-old truth: the truly powerful strength, support, and love that family members can provide to one another.”

As you can see in this photo, while Erika Smalls might not be as big of a name as her top-model sister Joan, the two compliment one another incredibly – something that might add to Erika’s growing portfolio.
