Have you noticed the 2000s trend making a serious resurgence at the beach and pool this year? The triangle bikini is back! But, to be clear, this is not the basic, string swimsuit of your high school years. The 2021 triangle bikini has been reinvented in fun textures (think crotchet and metallic), with tie fronts and ruching details. Some styles even forego the signature string look entirely — utilizing hooks and fastenings instead to minimize tan lines.

Not only is the triangle bikini popping up at vacation spots across the globe, but the itty-bitty swimsuit is creating waves on social media among influencers and A-listers — including Dua Lipa, Hailey Bieber, Lizzo, Kylie Jenner, Jennifer Lopez, and Sophie Turner — who are opting for triangle silhouettes over other modern styles. Plus, TikTok members are using triangle tops for viral swimwear hacks, showcasing how to nail the "upside-down triangle bikini" trend.

The great thing about triangle bikinis is that they reduce unwanted tan lines, have customizable strings for a perfect fit (no matter your bust size), and can be adjusted for added coverage or to reveal side boob if that's your thing. Keep scrolling for the best triangle bikinis and triangle bikini sets from high-end brands including Vitamin A and Mikoh to affordable options on Amazon. (

One reviewer wrote: "I love the extra-long strings to wrap around the torso!! Especially since it's one continuous line instead of detached like some other suits might be made. I also love that it's a bit cheekier, but not so much that the bottom half feels too little. It's just right."

Triangl Vinca Set

Hailey Bieber is a fan of Australian swimwear brand Triangl, and has been spotted in several of its suits, including a super cute pink triangle silhouette on her social media.

While it might be simple, you can't go wrong with a classic triangle bikini — as proven by Kim Kardashian. This set has more than 3,500 five-star ratings from Amazon shoppers, and features removable pads and customizable string ties at the neck and beneath the bust. One shopper said they were on the hunt for a basic triangle bikini they could tie different ways as seen in Tiktok bikini top hacks — and this one fit the bill.

"I've tried probably 10+ bathing suits from Amazon looking to find one that fits right, is not a thong, has padding, and ties on the sides, and this is it. I bought it in black also because I love how it fits so much. It still has a cheeky bottom but it provides far more coverage than any suit I've purchased within the last few years. I highly recommend this suit!" said a fan.

One reviewer wrote: "I love this so much! As someone with a larger chest (34F/34DDD) and whose tiny everywhere else, a good bikini is hard to find. The top has removable cups so you can choose to keep them in or not. My boobs feel secured in this top and it feels like nothing will spill out or pop out accidentally. I'm usually a medium in bottoms but I ordered a large because of my chest size and I'm so glad I did! The bottoms are cheeky so I felt like if I ordered a medium, they'd be sucked into the abyss of my booty, so I'm glad I sized up!"
