Millie Bobby Brown’s Best Bikini Moments Through the Years

There’s no doubt fans of Millie Bobby Brown know her best for her portrayal of Eleven in the Netflix series Stranger Things. While the role is doubt the 22-year-old star’s most well-known one to date, the British actor is also a producer, entrepreneur, wife and mom.
With roles in films like Enola Holmes and Godzilla: King of the Monsters, Brown is making a name for herself on the big screen. She’s also a published author, having released her novel, Nineteen Steps, in 2023. As for her business ventures, there’s not really a sector Brown hasn’t broken into yet. She’s the founder of beauty brand Florence by Mills, as well as Florence by Mills Coffee and Florence by Mills Fashion.
It’s understandable that when she’s not filming or making major business decisions, Brown likes to enjoy her downtime—and if her Instagram account is anything to judge by, much of that relaxation happens at the beach. Below, we’re taking a closer look at just a few of Brown’s standout bikini moments over the years.
Western-inspired accessories
In July, Brown amped up a brown underwire bikini top with some statement accessories, including a cowboy hat and a wide belt-scarf combo worn at her waist. She appropriately deemed the look “coastal cowgirl.”

Sunbathing and skincare
The only thing better than a sunny afternoon spent by the shore? One in which you can also incorporate some skincare, which Brown did on multiple occasions this past summer, thanks to her brand’s Pineapple Whip Moisturizer ($20).
Vacationing in Turks and Caicos
During the spring of 2025, Brown shared a carousel of Instagram pics, including this beachfront snap taken at Pearls of Long Bay, an estate in Turks and Caicos.
Major cool girl energy
Brown accented her pink patterned string suit with a pair of denim from her own brand, and accessorized with some oversized shades as she posed against a wall.
Sweet as a cherry
Brown declared herself in a “Cherry lips, crystal skies” mood while rocking a fruit-adjacent two-piece for a few snapshots in the sand.

Declarations of love

What’s next for Brown?
While Enola Holmes 3 hit Netflix in July, the actor is attached to several forthcoming projects, including Just Picture It and Prism. She will also reunite with her Stranger Things costar David Harbour in a yet-to-be-titled spy-drama series that they will both star in and executive produce.
In addition to her professional pursuits, Brown is enjoying motherhood as she recently became a proud mom of two. Last month, she and her husband announced that they recently welcomed a son.
