Sydney Sweeney is one of the most popular, in-demand actresses 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 28-year-old Washington native is a force to be reckoned with, using her talent and large following to also 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.

Becoming a household name over the years, Sweeney has established herself as a talented actress 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.

Life in the spotlight allows for 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 Magazine 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

Sweeney doesn’t tend to shy away when it comes to sharing life updates with her whopping 25.3 million followers (and counting!), from trips with friends to exciting brand collaborations and everything in between. Be sure to bookmark this post as you’re creating your 2026 swimwear vision board for the year ahead. We definitely will. As evidenced in the photos above, the Reality actress experiments with different colors and styles, inspiring us to do the same.

As for what’s next for this talented actress, she will star in and executive produce the adaptation of the best-selling novel The Housemaid by Freida McFadden, directed by Paul Feig, out on Dec. 19, 2025. And early next year, the highly-anticipated third season of Euphoria will drop in spring 2026.
