In the summer of 2025, the classic triangle bikini is experiencing a significant resurgence, marking a departure from the unconventional “upside-down” trend that dominated swimwear fashion in 2022. This shift towards simplicity and timeless design is largely influenced by early adopters like Kendall Jenner, who have returned to the traditional style after the novelty of previous trends waned.
The iconic ’90s triangle bikini, characterized by its minimalistic aesthetics—two simple triangular cups with string tie closures around the neck and under the bust, paired with low-rise bottoms with side ties—is making a strong comeback. This revival emphasizes a relaxed, effortless look, favoring classic colors like black, white, and chocolate brown. Subtle embellishments such as studs, shimmery fabrics, crochet textures, or playful prints are also being embraced, with celebrities like Kylie Jenner and Dua Lipa showcasing these variations during their summer getaways.
Kendall Jenner, a prominent fashion influencer, has been at the forefront of this trend. She has been seen sporting traditional triangle bikinis in various settings, including a red and white striped thong bikini during her European vacation, embodying effortless summer style. Her fashion choices reflect a return to classic swimwear silhouettes, moving away from more experimental designs.
Kylie Jenner has also been instrumental in popularizing the triangle bikini’s return. During her Italian vacation, she showcased a vintage Ralph Lauren leather polka dot ensemble, including a triangle bra, highlighting the blend of classic patterns with modern styling. Her social media posts have featured a variety of triangle bikini styles, reinforcing the trend’s versatility and appeal.
Dua Lipa, known for her bold fashion choices, has embraced the triangle bikini trend with her unique flair. On her beachside vacation in Italy and Spain, she wore a black triangle bikini adorned with sparkly silver studs, pairing it with a sheer black lace wrap skirt. Her choice of accessories and styling underscores the triangle bikini’s adaptability to different fashion sensibilities.
The triangle bikini’s resurgence is not limited to celebrity endorsements. Fashion brands are responding to the renewed interest by offering updated versions of the classic design. For instance, the swimwear brand Heavy Manners, favored by both Kendall Jenner and Dua Lipa, has launched a fresh lineup of solid-colored bikinis, including their signature stringy triangle designs. These offerings cater to the demand for minimalist yet stylish swimwear options.
The trend also reflects a broader movement towards embracing vintage-inspired fashion. Designers are incorporating elements from past decades, such as polka dots and crochet textures, into modern swimwear collections. This fusion of retro and contemporary styles resonates with consumers seeking both nostalgia and current fashion relevance.
In addition to aesthetic appeal, the triangle bikini’s design offers practical benefits. Its adjustable ties and minimal coverage provide a customizable fit, catering to various body types and personal preferences. This adaptability contributes to its enduring popularity and widespread adoption.
As summer 2025 progresses, the triangle bikini stands out as a symbol of the fashion world’s cyclical nature, where classic styles are continually reimagined and reintroduced. Its comeback underscores a collective appreciation for simplicity, versatility, and timeless design in swimwear fashion.
