Halloween is behind us, which means the holiday season has officially arrived — and Calvin Klein is bringing the festive cheer with its brand new holiday campaign starring Hailey Bieber and Brandon Flynn.

The iconic clothing brand tapped the model and actor to star in the photo shoot wearing a modern interpretation of festive dressing — everything from trendy slip dresses to cozy sweaters. The brand calls the shoot a celebration of the giving season, showing Bieber and Flynn in full-on joyful mode as we enter the holiday months.

Calvin Klein took PEOPLE behind the scenes of Bieber’s shoot for a selection of exclusive photos of the model as she dressed up in her holiday best. Bieber, 26, dressed up in looks from CK’s holiday womenswear collection, including a calf-skimming satin slip dress that’s right on trend for the ’90s vibe.

She also wore an oversize black suit for a few shots that’s just sexy enough to wear to all of your holiday parties but still appropriate to wear to your work fetes too. The slouchy look feels modern and chic with a sophisticated twist that Calvin Klein is bringing to each of its holiday pieces.

The campaign was directed and shot by James Brodribb, while the behind-the-scenes shots were handled by Alithea Castillo & Kim Tin. The team oversaw Bieber while she went from cozy knit looks perfect for lounging by a fire to night-out looks with the girls, demonstrating the versatility of CK’s newest holiday-wear.

Bieber is no stranger to modeling for the iconic American brand. Back in 2019, she and husband Justin Bieber stripped down to their Calvins to celebrate the label’s 50th anniversary collection. They also shared a steamy makeout session in the “anthem video” created for the brand’s birthday.

In the sexy ads, the couple modeled new underwear pieces from the CK50 anniversary collection, a limited-edition capsule of intimates and athleisure styles featuring a special CK50 logo. The Biebers posed in a number of loving — and totally steamy — positions to show off the looks.

That campaign, photographed by Glen Luchford, also starred A$AP Rocky, Kendall Jenner, Troye Sivan, Liu Wen, Parker Van Noord and Rebecca Leigh Longendyke.

“The campaign captures the rebellious spirit that has shaped the brand over the last 50 years,” the brand shared in a statement at the time.
