Meta Description: TA3 swimwear has taken the internet by storm with its patented waist-snatching technology. Read our honest TA3 review covering fit, sizing, celebrity fans, and whether this sculpting swimsuit lives up to the hype.
Introduction: The Swimsuit That Finally Answers the Question No One Asked—Until Now
Here’s a question that might stop you mid-scroll: Why do we wear shapewear under our clothes, but when we’re most exposed, we wear the flimsiest, most shapeless garments ever?
Leila Shams, the founder of TA3, asked herself that exact question. And she spent nearly three years and hundreds of prototypes trying to answer it.
The result? A swimsuit that doesn’t just make you look good—it makes you feel like a completely different person the moment you pull the strings. If you’ve spent even five minutes on TikTok or Instagram in the past two years, you’ve probably seen the viral videos: a woman slips into a TA3 one-piece, reaches behind her back, pulls two cords, and—voilà—her waist instantly cinches, her curves appear, and her confidence visibly skyrockets.
But here’s the thing about viral products: they’re not always worth the hype. So before you drop $178+ on a swimsuit, let’s dive deep into everything you need to know about TA3—the patented technology, the celebrity fans, the real-world results, and whether this sculpting swimwear actually delivers on its promises.
What Is TA3? The Brand Behind the Viral Sensation
TA3 Inc. (doing business as TA3 Swim) is an American swimwear company founded in Los Angeles, California, in 2019 by fashion designer Leila Shams. Shams, who had been a fashion designer for 25 years and worked with some of the biggest names in the industry, was tired of ill-fitting, unsupportive swimsuits that destroyed her confidence.
The brand’s name? It’s short for “Tres” (three in Spanish/French), representing the three areas the brand focuses on sculpting: the waist, the bust, and the hips.
What started as a personal mission quickly became a cultural phenomenon. TA3 gained massive momentum after Shams appeared on Season 13 of Shark Tank—and while she didn’t secure a deal, the exposure was invaluable. But the real turning point came on TikTok, where videos of shoppers tightening the corset-style back lacing racked up millions of views.
Today, TA3 has an annual revenue of over $20 million, holds one utility patent and 18 design patents, and has been worn by celebrities including Beyoncé, Billie Eilish, Sydney Sweeney, Ashley Graham, Drew Barrymore, and Bebe Rexha.
The Secret Sauce: How TA3’s Patented Technology Works
The “Snatch” Mechanism
At the heart of every TA3 swimsuit is what the brand calls “mega-sculpting” technology. Unlike standard swimwear that simply covers your body, TA3 suits are meticulously crafted to provide unparalleled support, lifting, shaping, and smoothing.
The signature feature? A lace-up back that works like a corset—but without the discomfort. Here’s how it works:
You slip into the suit like you would any one-piece.
You reach behind your back and grab the two strings.
You pull—as hard or as gently as you want.
The waist cinches instantly, creating an hourglass silhouette.
This isn’t just clever marketing. The design is protected by U.S. Patent No. 12,059,044 and CA 3,158,543, which cover the shaping technology, compressive material, and the lacing/back panel.
The Fabric Difference
TA3 suits are made from a lightweight activewear compression material that’s both sturdy and comfortable. Unlike cheap shapewear that leaves you gasping for air, the fabric moves with you—no squeezing, no fuss.
The brand also offers UPF 50+ sun protection in many styles, making these suits as practical as they are flattering.
TA3 Product Line: Which Suit Is Right for You?
TA3 has expanded far beyond its original one-piece. Here’s a breakdown of the most popular styles:
The Plungey
The brand’s best-selling style, featuring a flattering deep-V neckline. Available in sizes XXS to 3X with multiple fit options. Supports up to a K cup—almost unheard of in the swimsuit world. Priced around $178.
The Lifty
Designed for shoppers who want maximum lift and support. Features underwire, unlined cups, and thicker straps—essentially the support of a bra in a swimsuit. Available in cup sizes A to J/K. Prevents the dreaded “uniboob” that plagues many one-piece suits.
The Surfy
A sportier option with a plunge neckline that can be adjusted to your liking. Features built-in shapewear and UPF 50+ sun protection. Available in seven different colors.
The Lacey
A more affordable entry point at $89, available in sizes XS-3X. Offers compressive smoothing fabric without the higher price tag.
Postpartum Collection
TA3 also offers an entire line designed for new moms, featuring ultra-sculpting compression, adjustable shaping, and built-in bust support—perfect for postpartum bodies. Many styles feature zipper fronts for easy breastfeeding access.
Sizing: Where TA3 Truly Stands Out
One of the biggest complaints women have about swimsuit shopping? Nothing ever fits right.
TA3 addresses this with an unprecedented level of customization:
Three Torso Lengths
Most styles come in Short, Regular/Long, and Extra Long. This is a game-changer for petite women who usually deal with bunching and gaping, and for tall women who struggle to find suits that don’t ride up.
Cup-Size Options
Some styles, like the Lifty, come in specific cup-size ranges up to J/K. Others have adjustable straps and removable pads for a customized fit.
Size Range
TA3 offers sizes from XXS to 4X, making it one of the most size-inclusive swimwear brands on the market.
Butt Coverage Options
You can also choose your preferred level of coverage, from cheeky to full.
According to Business Insider’s testing, the suits fit true to size overall, but the torso and bust options make the biggest difference in achieving a perfect fit.
Real-World Results: What Reviewers Are Saying
The Good
“I feel like a catfish” — This was one tester’s honest reaction after trying on a TA3 suit for Business Insider. And she meant it as a compliment.
“Before TA3, I always felt like I needed to cover up when I was at the pool. With TA3, those feelings are gone.” — NY Post reviewer
“TA3 changed my mind about that and gave me that long-lost summer body confidence that I thought was the stuff of myths.” — NY Post
“The suit gave me curves I’ve never seen.” — Trustpilot reviewer
“I love all of my TA3 swimsuits, but the Lifty suit is my favorite because the underwire is so supportive and prevents the dreaded uniboob.” — Business Insider
Multiple reviewers have noted that these suits are built to last. One Business Insider editor noted that she’s still wearing suits she bought back in 2022, making the $178+ price tag more justifiable.
The Considerations
Price: At $89-$188+, TA3 is undeniably an investment piece. But as one reviewer put it: “Given how sturdy the construction is, I suspect it’s going to last me a really long time”.
Quality Consistency: Some long-time customers have noted that newer releases don’t quite match the quality and weight of older pieces.
Return Policy: Refunds cost $9.95 (or $5.99 per item for 3+ items) unless you add Free Returns + Package Protection at checkout.
The Celebrity Stamp of Approval
When Beyoncé wears your swimsuit, you know you’ve made it.
TA3 has been spotted on:
Beyoncé
Billie Eilish
Sydney Sweeney (who wore the Hi Cut Sleeveless Surfy on her birthday trip)
Ashley Graham
Drew Barrymore
Bethenny Frankel
Celebrity endorsements don’t automatically make a product great. But when multiple A-listers choose the same brand—especially for something as personal as swimwear—it’s worth paying attention.
TA3 vs. Competitors: How Does It Stack Up?
TA3 vs. Standard Shapewear Swimsuits
Most “tummy control” swimsuits use bonded linings that are tighter and less stretchy than the outer fabric. TA3 uses an adjustable lace-up system that lets you control the level of compression. You’re not stuck with one level of tightness—you can cinch as much or as little as you want.
TA3 vs. Corset Swimwear
Traditional corset swimwear can be uncomfortable and restrictive. TA3 uses activewear compression material that moves with you while still providing that snatched silhouette.
TA3 vs. Budget Dupes
Yes, there are TA3 dupes available at lower price points. But reviewers consistently note that the quality, durability, and sculpting power of the original far surpass the knockoffs.
The “Lazy Girl’s Guide to Hotness” Campaign
In 2025, TA3 launched its first major creative campaign, “The Lazy Girl’s Guide to Hotness,” created with ad agency Pereira O’Dell.
The campaign was inspired by viral #LazyGirlAesthetic and #HotGirlsWhoEat trends, which have garnered over 140 million and 200 million views on social media, respectively. The message? You don’t have to work hard to look hot—you just need the right swimsuit.
It’s a brilliant positioning that taps into exactly what makes TA3 so appealing: effortless transformation.
