Why Stranger Things’ quiet star has become fashion’s new luxury muse

It’s been a long wait, but the second part of ‘Stranger Things 5’ is finally here. Crowned as the most-watched series in Netflix history, this fifth season has been split into three parts, with the finale arriving on January 1, featuring a last episode with a runtime similar to that of a feature film, a formula the Duffer brothers have used before.

It was in 2017 when Sadie Sink joined the cast to play Max. At the time, the actress was 14 years old, and although hers was not a leading role, she achieved overwhelming fame that she maintains to this day. 

There is something especially curious about her rise to fame. The Texas native almost always plays supporting characters on screen, yet she has still managed to make the fashion world fall at her feet.

She works with Molly Dickson, one of Hollywood’s most sought-after stylists. She is the face of brands such as Prada and has collaborated with Chopard and Chanel, and she never missed a show during the major fashion weeks. 

“Her style is a very well-crafted blend of youthful sophistication and contemporary minimalism. She has a quiet but magnetic presence,” explains Maripi Robles, an expert in communication, branding, and fashion culture. “She opts for clean lines, refined silhouettes, and a very controlled palette, which makes her a perfect canvas for modern luxury.”

Proof of this was the promotional appearances the ‘Stranger Things’ cast has made in recent weeks, where Sadie Sink managed to stand out precisely without extravagance: she was the only one among her co-stars to opt for white, wearing minimalist creations signed by Prada.

“She has a defined style, appropriate for her age yet versatile, which allows her to stand out,” notes stylist Ángela Calderón Morata. 

The secret of her style:

Although 2025 has been the year in which the runway has tried to bring back seventies maximalism, it is precisely the opposite aesthetic current that seems to work for the actress. 

“The most attractive thing about Sadie Sink’s style is her ability to project a silent sophistication. She doesn’t compete for the spotlight, but when she appears, she brings a very clear, very polished presence that fits impeccably with the codes of contemporary luxury,” says Maripi Robles.

 “She has something brands value highly: a natural elegance that doesn’t seem constructed, but innate. At a time when luxury wants to connect with new generations without losing its aura, Sadie is the ideal balance.”

“She has something brands value greatly: a natural elegance that doesn’t seem constructed, but innate,” she added. Her (relatively) unconventional appearance also stands out, with her striking red hair and very natural features that help her connect with the public. 

“It matters because these aren’t typical features. Her look is refined and delicate. Today, beauty in difference stands out, and brands are looking to break stigmas and conventional standards,” says Ángela Calderón.

New priorities in the fashion world:

Experts have long been pointing out that luxury has reoriented its strategy toward a much younger audience. A report by Boston Consulting Group notes that Generation Z (those born between 1997 and 2012) will go from accounting for just 4% of global luxury spending to 25% by 2030.

These are clients brands want to approach, betting on a change in how they communicate. “They are focusing on reaching a younger audience to achieve greater projection and reach,” explains the stylist.

This has been demonstrated, for example, by betting on the K-pop phenomenon, appointing its singers as global ambassadors. Felix (Stray Kids) is a global face of Louis Vuitton, Jennie (Blackpink) is a Chanel ambassador, and Jimin (BTS) represents Dior. 

Within this same movement fits Sadie Sink, who is a young figure with her own aesthetic, capable of connecting with a twenty-something audience like herself.

“It suits brands far better for their ambassadors to maintain a personal and authentic style, rather than forcing trends.” At this point, experts agree that Sadie Sink’s value for luxury brands is not limited to her image, but also to the coherence with which she projects it. 

“It suits brands far better for their ambassadors to maintain a personal and authentic style,” says Maripi Robles. For her, the key is that the actress doesn’t force trends or get carried away by what’s viral.

Her way of dressing flows naturally, makes sense with her personality, and conveys a very distinctive elegance, something luxury especially values when building a long-term relationship.

Ángela Calderón adds that this authenticity is not at odds with adaptability. “Brands look for representatives with their own style, but also capable of evolving and embracing new trends without losing their essence.” And that balance between personality and versatility is precisely what makes Sadie Sink such a coveted ambassador.
