There's nothing US stars love more than celebrating the 4th July in fashion, but as parties take place in the height of summer there's only one place to hold the festivities: poolside. These celebs got in the mood for some summer fun with bikinis that gave a nod to the occasion – or took a more on-the-nose approach to stars and stripes.
Read on to see the most iconic 4th July bikini picks from over the years...
Demi Moore
Eighties Brat Pack icon Demi Moore celebrated 4th July 2023 in a blue bikini paired with the perfect accessory: her adorable dog Pilaf. Captioning the post, "Happy Independence Day! Don't forget your SPF", Demi ticked off stylish and responsible summer sun protection in one.
Complete with a relaxed smile and her tiny puppy cradled in hand, Demi aced poolside dressing for a relaxed Independence Day celebration in the sunshine.
Katherine Schwarzenegger
Katherine Schwarzenegger is best known for her New York Times Bestsellers and her movie-star marriage to Marvel leading man Chris Pratt. But you might not know she's also provided some iconic fashion inspo, including her 4th July look for 2026.
A cute red gingham pattern kept things classic, while Katherine casually snapped a mirror selfie at home. Her other photos spotlighted the family's day of fun, complete with temporary tattoos and coordinated outfits.
Sofia Richie
In 2023, Sofia Richie proved that 4th July bikini styling doesn't have to go all-in on Americana, donning a navy polka-dot bikini that didn't distract from the blue ocean around her. Instead, the model posted some sweet highlights from her trip away that captured organic summer moments rather than organised festivities.
Only Sofia could pull off looking that relaxed while balancing on a paddleboard, leaning back without a care in the world. A reminder to her fans that you don't need Pinterest-ready charcuterie boards or flag-themed cupcakes to have a good time, perhaps? Simply enjoying the summer sun is just as good a way as any to celebrate!
Rumer Willis

But one of her most iconic moments in fashion was the height of Americana, pairing a Stars and Stripes bikini top with distressed denim shorts.
She brought Hollywood confidence to the outfit that picked up on key trends of the 2010s, still making it work a decade on from the years spent hacking at your favourite jeans with a pair of scissors.
Holly Madison

She was also on hosting duties at the MGM Grand Hotel, but all seemed to be in hand as she modelled her summer leisure look.
A monotone bikini might not scream Independence Day decadence, but the bright red ensured Holly was perfectly coordinated to the US flag while keeping things cool and classic.
Katy Perry
Katy Perry has had some iconic fashion moments in the past and has a particular affinity for '50s American fashion. It was no surprise then when she marked 4th July 2024 with a Rosie the Riveter-inspired look, swapping working overalls for a flag-influenced bikini and jeans.
The singer also gave a shout out to her single from her 2024 album 143, Women's World, proving that for some celebs life and work intersect, even on a public holiday.
Elizabeth Banks
The Charlie's Angels and Spider-Man star pulled out all the stops in 2024, sharing a sweet video of the celeb enjoying Massachusetts' celebrations, complete with a large summer hat, sunglasses and, of course, a Stars and Stripes bikini.
Elizabeth appeared to be loving life, enjoying time in the sun and watching a carnival of performers, including an inflatable shark and musicians dressed up like revolutionaries from the eighteenth century.
