Sydney Sweeney stars in Home Alone-inspired SYRN holiday campaign

Sydney Sweeney is getting into the Christmas spirit with a little help from Kevin McCallister.

The “Euphoria” star recreated several memorable moments from the 1990 holiday classic “Home Alone” in a playful new advertisement for her lingerie and loungewear brand, Syrn.

In the beginning of the video, Sweeney stood in front of a bathroom mirror wearing a plunging navy blue top beneath a cropped cardigan, with her blonde hair styled in loose waves.

Sweeney then splashed a liquid onto her face before placing both hands against her cheeks and letting out a dramatic scream, recreating the iconic moment when Kevin McCallister applies aftershave in the 1990 Christmas classic.

Sweeney continued the holiday tribute in another scene, this time wearing a burgundy loungewear set while holding a small white dog.

As a shadowy figure appeared behind a curtain, the actress widened her eyes in alarm, adding another playful nod to the movie’s home invasion storyline.

Another moment showed Sweeney enjoying a towering ice cream sundae topped with whipped cream, recalling the dessert Kevin treats himself to while enjoying the house without his family.

The video is the latest installment in Sweeney’s holiday campaign for Syrn, which has drawn inspiration from several Christmas classics.

In an earlier promotional video shared on the brand’s Instagram account, Sweeney modeled looks inspired by Cindy Lou Who from “How the Grinch Stole Christmas” and characters from “The Nightmare Before Christmas.”

The latest release, called Hibernation Nation, is part of the brand’s holiday offerings and features cozy loungewear.

Sweeney launched Syrn in January, expanding her career beyond acting and producing.

In a January interview with Cosmopolitan, Sweeney discussed her approach to creating lingerie for different body types.

“My designers are all women, and I have an amazing diverse team,” she told the magazine.

“My models are a beautiful range of body types. I’m always like, ‘I want to see it on every body.’ I can’t be the only model. I need to make sure everyone feels really good in it.

“If I wouldn’t wear it, I wouldn’t want to make it.”

Sweeney also revealed that her own experiences shopping for lingerie influenced the brand’s designs.

“In sixth grade, I was a 32 DD, and I remember going to the store to get my first wire bra,” she told Cosmopolitan. “It was silk and the only bra I felt good in. I literally wore it to the point that it had holes in it.”

She explained that she eventually brought the bra into her Syrn office as an example of the kind of lasting comfort she wanted to create for customers.
