Charli XCX has always known how to make a moment — and in 2026, she's doing it in a bikini. From the promo campaign for her A24 mockumentary The Moment to a surprise spa day drop, Charli has been serving black bikini energy like it's a personal manifesto. Brat summer never really ended, y'all. It just got a swimsuit.
The Moment That Started It All: Charli and Kylie in Matching Black Bikinis
When A24 wanted to launch tickets for The Moment, a mockumentary exploring the cultural explosion of Charli XCX's "Brat" era, they didn't do a boring press release. They sent Charli and her co-star Kylie Jenner out in matching black bikinis — and the internet lost its mind.

Jenner went latex triangle top with high-cut bottoms and a white robe. Charli matched her in a black string bikini with gold hardware detail — slightly skimpier, because of course. Both wore their dark hair loosely down and finished the look with oversized shades. It was promotional content that doubled as a fashion moment, and it set the tone for everything that followed.
The Moment (directed with an A24 eye for chaos and culture) also features Alexander Skarsgård and Rachel Sennott, but honestly? No one was talking about them after this promo drop. Charli in a bikini has a way of commanding the entire conversation.
From Sundance to the Spa: Her Bikini Looks Keep Coming
Charli's bikini run in early 2026 wasn't just one moment — it was a whole era. At Sundance, she posed against a backdrop of snow-covered mountains wearing a floor-length brown fur coat left casually open at the front to reveal a black bikini set underneath, champagne flute in hand. The contrast was very Charli: completely chaotic, totally confident, and somehow extremely chic.
Then came the spa day drop. Charli shared a carousel on Instagram mid-film-launch featuring a chic black bikini top with a distinctive swirl design and a stylish halter neckline, layered with a white spa robe hanging off her waist. It was the kind of "I'm relaxing but make it fashion" content her 15 million followers have come to expect — and fans went predictably feral in the comments.
The Premiere: Bikini Bottoms as a Fashion Statement
For the UK premiere of The Moment, Charli leaned all the way into her signature maximalist-minimalist paradox: black bikini bottoms, a zip-up jacket with a cinched waist, towering thigh-high boots, and silver jewelry. It was daring, it was unpredictable, and it absolutely worked.

It's a look that says: I know exactly what I'm doing. Charli's bikini-as-outfit approach has been one of the most talked-about red carpet moments of early 2026, and the styling inspo is everywhere. The jacket-over-bikini aesthetic isn't just for Sundance anymore — it's a full 2026 move that you can absolutely steal.
Get the Look: Charli's Black Bikini Energy, Under $60
The brat aesthetic is built on confidence, contrast, and not trying too hard — which is exactly the vibe of Audi Swim's Bow Babe Contrast Top in Black ($30). That white contrast trim on a black base hits the same note as Charli's gold hardware detailing — bold without being loud. Pair it with the Bow Babe Contrast Bottoms in Black ($30) for a complete set that's built for both the beach and the 'gram.
Want to channel the jacket-over-bikini premiere look? Layer the set under the Ocean Mist Maxi Dress ($30) — a sheer, flowy cover-up that gives that same intentional "this is a look" energy. Throw it over your black bikini, add some gold jewelry, and you've got the outfit. The full set runs $60 total, which is extremely brat of you.
Why Charli XCX Is the Celebrity Swimwear Moment of 2026
What makes Charli's bikini run different from a typical celebrity beach photo is the intentionality. Every look has been styled, shot, and dropped with purpose. She's not just showing up at a pool — she's using swimwear as a costume, a character choice, a mood board for the brat era. That's a level of creative control that her audience and the fashion world deeply respond to.
It also confirms what we've been seeing all year: black bikinis are the defining swimwear moment of 2026.
