Keeping up with the Clauses.

Kim Kardashian rounded up all four of her sisters for Skims’ new holiday campaign — a midcentury Christmas-themed affair with a few choice cameos from Santa Claus.

For the shoot, the siblings posed in festive wares from the brand’s Holiday Shop in a home decked out with tinsel trees, wrapped presents and a cozy fire.

Photographer Nadia Lee Cohen (a favorite of the Kardashian-Jenner clan) captured Kim under the mistletoe in a plunging dress covered in prancing reindeer.

Kylie, fresh off her Victoria’s Secret Fashion Show debut, traded her $50 million Fantasy Bra for a Fair Isle knit bralette and micro-miniskirt.

Kendall likewise stripped down for the season, pairing her bouffant and sheer stockings with a plaid bralette and matching thong.

Khloé looked ready for a long winter’s nap, curled up in a onesie and matching hat. Kourtney, meanwhile, gave the gift pile some competition, lounging by the hearth in leggings and scarlet pumps.

As for the man of the hour? Santa played pillow for Kim, who rested her head on his knee in coordinating pajamas and heels.

Skims’ Holiday Shop goes live Oct. 29 and puts a Kardashian-coded spin on the season: one print features a shiny pink sports car wrapped in a bow, and the lineup includes sheer lace stockings and silky slips along with fuzzy sweats.

Kim has tapped her siblings as models before. Kendall and Kylie modeled Skims lingerie for Valentine’s Day back in 2021, prompting Kourtney to Photoshop herself into a shot on Instagram Stories (“Since I wasn’t invited,” she joked).

The brand’s holiday campaigns have drawn a varied guest list over the years, from Snoop Dogg and his family to Tate McRae to Kim’s daughter North West.
