Kim Kardashian is a jack of all trades ...

she's modeling a new offering from her SKIMS brand, starring in an ad campaign for a collab with Dolce & Gabbana ...

with an assist from her sister. Kim K just dropped the first look at her SKIMS x D&G collection, and she's styling the sexy clothes alongside Kourtney Kardashian . Waiting for your permission to load the Instagram Media.

The sisters are getting wild in the photo shoot with matching leopard-print catsuits ...

and they also model some leopard-print bras, tops and leggings. Rawr!!! Kim's leaning hard into Italian imagery here ..

. playing up the Italian luxury fashion house's roots. Looks like Kim's new collection also includes some plain white bras and panties, plus a black corset dress and a black mesh bodysuit.

Behind the scenes photos show Kim getting glammed up in hair and makeup ...

and photographer Nadia Lee Cohen even shared some outtakes, featuring a smiling Kim. Kim enlisting Kourtney for the ad campaign is interesting ..

. because last year, Kourtney called Kim an egotistical, selfish witch in an episode of their Hulu show, "The Kardashians." It seems the beef has been squashed!!! Kim says her limited-edition collection drops next Tuesday at 9 AM ET online, in SKIMS stores and select Dolce & Gabbana boutiques .

.. and like anything she touches, it's sure to sell out quick.
