It was the summer of 2022, and the triangle bikini was enjoying an era of glory, but fashion had turned it on its head. The so-called upside-down bikini revolutionized social media and vacations, with not a single account missing this original and rebellious way of tying it, with the apex facing the sides and the traditional bottom now creating a somewhat peculiar neckline.
At the time, the trend spread like wildfire, even if it wasn't always flattering or comfortable. But in this era, everyone wants to be different…even if that means ending up in a uniform and dressing exactly the same as everyone else. Such are the paradoxes of life—and fashion.
However, everything points to the game being over for upside-down bikinis. Especially because those who pioneered this trend are among the first to abandon it. It seems early adopters are exhausted of seeing a crowd following their style recommendations and are looking to make an impact again, if this is still possible. The conclusion? Our beloved nineties bikini is back as we knew it.

The return of the old-fashioned tied triangle bikini.
One of the first clues came from Kendall Jenner, the same person who helped spread the trend we're abandoning today. It can't be a coincidence that over the past few weeks, she's started peppering her Instagram account with photos defending the traditional use of this two-piece.

In summer 2025, triangle bikinis are worn in the simplest way possible. Here's how you'll recognize it:
- Shape: The top is absolutely simple, with two triangular pieces and the drawstring running under the bust and around the neck. The matching bottoms are typically low-rise with side tie closures.
- Placement: As simple as possible. There's no attempt to close the neckline too tightly to bring the bust together. It's worn casually, as if we hadn't spent more than a few seconds throwing it on and adjusting it's placement.
- Colors: Although there are no particularly strict rules, we are especially seeing classic hues like black, white, or chocolate brown.
- Details: Here, there are some concessions, such as studs, shimmery '90s fabrics, or a crochet design. For her part, Kylie Jenner is doubling down on polka dots, while Dua Lipa has been adding lace, studs, and sparkly cheetah print to the equation.
If you feel like your neutral triangle bikini is missing something and want to add a special touch, you can do it with accessories. Hair scarves, raffia bags, thin chains around your neck that drape across your neckline... Let these elements set the trend while bikinis take a more relaxed summer.

The triangle bikini that has chosen summer 2025 may feel a little less exciting to wear than previous swimsuit trends. It's certainly less complicated, but... isn't that the key? Taking the hassle out of summertime seems like a very tempting idea.
