The 'Keeping Up With The Kardashians' star enjoyed being able to pose for Calvin Klein alongside her siblings - Kourtney Kardashian, Kim Kardashian West, Kendall Jenner and Kylie Jenner - and says they all really "feed off of each other" when they work together.
She shared: "I absolutely love working with my siblings. People might think we're crazy for that, but we really work better together and I think we really feed off of each other."
And the 33-year-old television personality was thrilled to be asked to pose for such an "iconic" brand.
Khloé added: "It's really out of this world to be shooting a campaign for Calvin Klein with all of my sisters; I don't think I ever thought this was going to happen. It's so iconic and such a legendary brand ... I've definitely been tearing Calvin Klein ads out of magazines and putting them on my mirror for inspiration or even for body goals, so to be asked to be a part of a brand that is so legendary is really dream-like."
And Kim feels "so lucky" to be working alongside her sisters too.
Speaking behind the scenes at the Calvin Klein shoot, Kim said: "We're so lucky to be shooting this together because we love being together - I think the day has been just a fun, sister catch-up time. Calvin Klein represents Americana and today's shoot totally fit together with the quilts and the barn and how chill it was - it just seems like the perfect fit."
