Beach Style Icon: See 6 Of Sydney Sweeney’s Most Revealing And Trend-Setting Bikinis

While Hollywood’s biggest film and TV productions feature plenty of stylish swimsuits, only a few on-screen outfits achieve genuine pop culture status. However, in recent years, one television moment earned its place in the swimwear Hall of Fame, courtesy of Sydney Sweeney and the second season of Euphoria. In a memorable scene, she walks down a flight of stairs in a bright, bubblegum-pink monokini featuring a cutout that exposes her midriff and straps wrapped around her waist. The suit reappears later in the infamous hot tub sequence (if you know, you know). This look caused a consumer frenzy, leading to the swimsuit selling out and accumulating a 500-person waitlist within a single day.

In her personal life, Sweeney possesses an even more remarkable seaside collection than her character Cassie’s (sorry, Cassie). Her closet is full of deeply plunging one-pieces, minimalist thong bikinis, and dazzling, jeweled sets. She solidified her status as a bona fide bikini expert by launching not one, but two collaborative collections with Frankies Bikinis in 2023.

With summer 2025 officially underway, Sweeney is back with her top-tier swim game. Therefore, now is the perfect moment to gather the Euphoria star’s most daring bikinis to provide inspiration for your next vacation.

Inspired by Lingerie

Following the huge success of Sweeney’s initial Frankies Bikinis launch in early 2023, she released a follow-up collection with even sexier options. A prime example is this navy blue set finished with lace trim, which could easily be mistaken for sensual undergarments—especially when paired with sheer stockings. Featuring detailed lace-up ties and satin bows, this outfit was a boldly provocative statement.

Patterned and Embellished

In the same collection, the Echo Valley actress demonstrated the appeal of a dazzling, jeweled look by the pool. She wore a white and blue floral top featuring a criss-cross halter design that highlighted her bustline. The coordinating V-shaped bottoms displayed the identical pattern and were edged with a row of beaded fringe. The look was playfully suggestive, adorned with ruffles, and chic in the best way.

A Low-Cut One-Piece

The Anyone But You star also has a strong affinity for stylish monokinis, particularly those with deep necklines that showcase the décolletage. She is known to favor this $99 swimsuit from Gooseberry Intimates, which she owns in green, white, and black. Her refined taste is approved by fellow celebrities, as this exact style has also been seen on Kendall Jenner, Jennifer Lopez, and Blake Lively, among others.

A Bold Utility Suit

Surfers traditionally value rash guards for utility rather than aesthetics, as this gear shields the wearer from the elements and chafing. Sweeney, however, skillfully blended style with practicality by donning a thong-style rash guard that exposed her backside. Embracing the daring vibe of the outfit, she captioned her social media post with the phrase: “I think they call this a thirst trap.”

A Perennial Favorite

Sweeney began 2025 the right way: enjoying a relaxing beach vacation that included a few water activities. She maintained a look that was both chic and enduring by selecting a triangle halter top and a tiny string bikini in a rich chocolate brown color. The style was simple yet sophisticated.

Western-Inspired Heat

The Cowboycore trend, fueled by Beyoncé’s influence, has finally made its way into swimwear—just look at Sweeney. The actress embraced the Western theme in her most recent campaign for HEYDUDE, where she modeled their sneakers while wearing a suede, tie-front one-piece that showcased both cleavage and sideboob. She completed the look by adding a cowboy hat for the full effect. Absolutely flawless.
