Sydney Sweeney is one of the most in-demand actors of the moment, starring in hit shows like Euphoria and The White Lotus as well as movies such as Anyone But You, Madame Web and Immaculate. Becoming a producer in 2023 through her company Fifty-Fifty Films, the Washington native is a force to be reckoned with, using her talent and large following to secure deals with big-name brands like Miu Miu, American Eagle, Kérastase, Armani Beauty, Laneige and Samsung. She’s appeared on the cover of Cosmopolitan, Variety, Vogue Hong Kong, Elle, Harper’s Bazaar and more.

As her career has continued to grow, Sweeney has established herself as a talented actor to watch and a go-to source of fashion inspo for women across the globe. From her glamorous red carpet ensembles to her everyday casual looks, the Spokane, Wash., native is always at the top of our lists when it comes to celebrity style. And in 2026, Sweeney added “brand founder” to her list of fashion accolades after launching SYRN: a chic, sultry lingerie and loungewear line.

Sydney Sweeney’s best bikini, swimsuit and seaside style moments

Because of this, Sweeney is one of our many celeb swimsuit muses—whether she’s modeling for a new collection or snapping pics from a recent getaway, she always looks stunning.

Life in the spotlight allows Sweeney to showcase her incredible sense of style, and she finds that clothing is a great way to express herself. “Fashion is a really fun way of embracing different sides of yourself,” Sweeney dished to People while promoting her collaboration with footwear brand HEYDUDE. “Some days, I might feel very girly, some days, I might feel edgy. Others, I might feel like I want to be more laid-back. It's a way of being able to express those different sides of how I feel or who I am.”

“It's always going to change,” she added. “That's what's so amazing, especially about being a woman, is being able to embrace all the different sides of ourselves, because we are so multifaceted and there's so much going on. I can never imagine being one thing for the rest of my life.” 

However, being an A-lister also comes with its drawbacks, and Sweeney has faced criticism for her wardrobe choices on the red carpet, as well as her appearance when she’s off duty. Last year, she told Variety that she doesn’t let the public discourse over her body bother her.

“I see it, and I just can’t allow myself to have a reaction,” she told the outlet. “I don’t know how to explain it—I’m still trying to figure it out myself. People feel connected and free to be able to speak about me in whatever way they want, because they believe that I’ve signed my life away. That I’m not on a human level anymore, because I’m an actor. That these characters are for everybody else, but then me as Sydney is not for me anymore. It’s this weird relationship that people have with me that I have no control or say over.”

What’s next for Sweeney: upcoming projects and more

The past year has been especially exciting for Sweeney, as she played an important role in the final season of Euphoria and unveiled her Honey Trap producing label in 2026. As noted above, she also launched her first clothing line, SYRN.

As for what’s next for the actor, she’s slated to star in several forthcoming films over the next couple of years, including The Custom of the Country, Gundam and the highly anticipated sequel to 2025’s The Housemaid, The Housemaid’s Secret.
