Finding a bra that fits perfectly is like the holy grail of shopping achievements. As every woman on the planet can attest, that’s no easy task: Studies have shown that a whopping 80 percent of us are wearing the wrong size. Different brands, styles, countries, and even fabrics can alter the fit and feel. But the fit isn’t the only thing you need to worry about on your quest—you also have to think about versatility, especially if you want to get the most bang for your buck. Luckily, the Internet has spoken and provided us with a universally loved T-shirt bra that has more than 33,000 glowing five-star reviews. ThirdLove’s 24/7 Classic T-Shirt Bra earns its spot as one of the best bras you’ll ever find for its impeccable balance of comfort and support. Along with the best bralettes and sports bras, this ThirdLove bra is an everyday essential you won’t know how you ever lived without. (Speaking of sports bras, did you hear ThirdLove launched a sports bra and leggings?)

Why ThirdLove’s lingerie business is thriving

This women-led company began disrupting the intimates market in 2013. Confronted with two choices for undergarments—be sexy or be comfortable—co-founders Heidi Zak and Ra’el Cohen set out to create a third option (hence, ThirdLove) that provided alternatives that looked good and felt good. They use millions of real women’s measurements and customer feedback to design their products to meet the needs of a diverse market. The company’s core beliefs center around the idea that every woman deserves to feel protected and confident. And you can feel extra good about your purchase: In an effort to give back, they’ve partnered with organizations such as I Support the Girls, Soles4Souls, Good360, and St. Anthony’s to help women in need. To date, they’ve donated over $40 million in bras.

What is a T-shirt bra?

Sure, it sounds self-explanatory, but this super popular design is actually ideal to wear with more than just T-shirts: It’s a perfect partner to don underneath blouses and shirts made of thinner fabrics, or anything with a snug fit since the cups aren’t designed with lace or design features that might show through your top. A T-shirt bra is traditionally a demi-cup (mid-coverage) that creates a seamless silhouette, no matter what you’re wearing. If you’re looking to hide visible bra lines, this reliable style disappears beneath any ensemble, as long as you have the perfect fit. Pro tip: Opt for this bra color that won’t show under white shirts. (It’s not nude!)

Why ThirdLove’s fan-favorite style is the best T-shirt bra

Since it was introduced seven years ago, the 24/7 Classic T-Shirt Bra has sold more than three million units and earned more than 33,000 five-star reviews. Ultra-thin memory foam cups provide comfortable, body-hugging support without adding any bulk. Pretty pleated straps with a no-slip lining stay put all day, without digging in. A double layer back with hidden elastic smooths your silhouette, and their label is printed on the foam padded hook-and-eye closure, which means no itchy tags!

Available in 13 colorways, it boasts the brand’s signature super-soft, smoothing microfiber fabric that’s knitted for maximum durability to withstand, as the name suggests, 24/7 wear. The newest iteration is made in breathable Pima cotton and features two-way convertible straps (worn either straight or racerback), gold alloy strap adjusters, and a stylish keyhole detail.

Size matters

“We are proud to be a category leader offering the most inclusive bra sizes,” says Cohen. That includes more than 80 sizes (double the amount of most other brands) from AA to I cups and 30 to 48 bands. In between cup sizes? The company invented half sizes for that very reason. It’s easy to find the perfect ThirdLove bra with their “Fit Finder” quiz, which more than 16 million women have already taken. The quick 60-second questionnaire promises to provide your ultimate brazier, and returns and exchanges are free for up to 60 days if you don’t love what you’ve bought.

It’s worth the investment

If you’re noticing these telltale signs you need a new bra, it’ll pay off to shell out some dough for a high-quality skivvy that’ll last for years. “A great-fitting bra can make all the difference, from how your clothes look to how comfortable you are,” says Cohen. Ill-fitting underpinnings can also be a pain—literally. From annoying underwires that can cause irritation to unsupportive styles that can create neck and shoulder soreness. The beauty of this ThirdLove bra (priced at $65) is that it works well with most breast shapes. The versatile style is ideal for any occasion, and, bonus points, the design naturally lifts and evens out fullness.

Women absolutely adore this ThirdLove bra

Don’t take our word for it—tens of thousands of happy customers swear by the magic of this ta-ta tamer. We aren’t exaggerating: More than 1,400 people use the phrase life-changing in their reviews. Larger-chested ladies like Liann P. writes, “I literally had tears of joy in my eyes when I first tried on this bra. Best investment ever. I feel like I am wearing nothing, and this is a big deal for a 40F. Will buy again.” Patricia echoed that sentiment, stating, “I am a large size, and this bra is great for me. It supports like no other bra before. My shoulders and lower back felt the relief instantly, and I didn’t want to rush home to take it off.”

And women of all sizes are sharing their success stories, including Deena, a 34F, who says, “This is the first time in eight years that I’ve had a bra that is comfortable! I went to all of the best shops to be professionally fitted. I spent my days being uncomfortable and had pretty much given up on being comfortable. I heard about ThirdLove and decided to take a chance. It’s so hard to believe that an app fitted me better than the famed department stores. I was so happy I bought two more! Oh, and also I don’t feel like I look like an old lady anymore!”

There are also countless accounts attesting to long-time wear and comfort. “I have never found a bra that I was willing to put on, and I dreaded long days at work in a bra. Now, I can work 15-hour days and I don’t even notice that I’m wearing one,” writes a reviewer named Geena. “This bra changed my life.” For more life-changing undergarments, check out the best shapewear for every body type and wardrobe need.
