8 best T-shirt bras
If you don’t notice a T-shirt bra, then you know it’s doing its job. But that doesn’t mean what you wear underneath a T-shirt, shirt or dress needs to be dull and uninspiring.
The best T-shirt bras aren’t noticeable under clothing, give the bust a smooth shape while offering support, and are beautifully designed.
But before you buy a bra, make sure it’s the right fit, as the size of your breasts can fluctuate due to hormone levels.
A trained salesperson in a lingerie store can help you out, but this can also be done at home with a tape measure.
If your breasts are spilling out of the cup or aren’t filling it, then it’s time for a new bra.
M&S Sumptuously Soft Ultimate Comfort T-Shirt Bra: £20, M&S
There’s a reason one in three British women wear M&S bras – they’re excellent. This one was without a doubt the most soft and comfortable bra we tried. The subtle, striped design and bow is just the right amount of pretty detailing to make you feel feminine, without being too fussy. The soft foam material not only provides the utmost comfort but gives a smooth shape and remains hidden under clothes.
Beija Flor For Keeps Y Bra: £50, Beija Flor
Beija Flor was founded in 2016 by two sisters who wanted to create go-to bras without compromising on style. We love this modern-looking bra, which is all about the details. It’s made from two pieces of material sewn together. The foam cotton triangles offer a little support, but create a natural look, rather than a “plunge” effect. And sewn over these is a soft, dark blue Italian mesh which also makes up the back strap, and extends to form thin shoulder straps. The fastenings and clasps – including a J hook which clips the two straps together to create a racer back – are a pretty rose gold colour. For those with a bigger bust, there’s also a For Keeps Z model which comes with underbra wiring and more structured cups.
Urban Outfitters Out From Under Ayden Scallop Triangle Bra: £22, Urban Outfitters
This bra is made from a combination of nylon and spandex, giving it a flexible, stretchy quality similar to that of a swimming costume. There are no clips at the back, but it pulls easily over the head. The scalloped edge is not only playful and stylish, but flattering because of how it embellishes the chest. The fabric is delicate and thin though, so it doesn’t give a great deal of support and may not be suitable for those with a larger chest size. But its feminine pattern makes it the ideal bra for wearing under a loose summer dress, or a top where it will peep out the sides.
Spanx Pillow Cup Signature Full Coverage Bra: £56, House Of Fraser
This one is a best-seller for Spanx and it’s clear to see why. It’s almost entirely seamless, with barely visible stitches securing the highly comfortable straps to the cup. The cup is lightly padded, but offers a little lift to the cleavage with the help of the underwire. Extra support is given by the wide back and thick shoulder straps – it’s so sturdy it almost feels like a secure sports bra. It’s a good option for those with a larger chest. Available in black and nude.
H&M 2-Pack T-Shirt Bras: £12.99, H&M
Considering the price, these bras are brilliant value. Perhaps they don’t quite offer the rock-solid support of higher end bras but they do create a smooth breast shape under clothing and are comfortable enough to wear all day. It’s a no-frills design but this bra does the job whether you’re wearing a work shirt or a skinny-fit T-shirt. Available in two different colour combos.
Rigby & Peller Marie Jo Avero Padded Black Bra: £75.95, Rigby & Peller
If a bra is good enough for the Queen, it’s good enough for us too. Her Majesty has reportedly been wearing Rigby & Peller bras her whole life, and this one certainly feels high quality – and you’d expect it for the price. With pretty daisy detailing on the straps, this bra is great for someone who wants something that isn’t obvious under your clothing but also isn’t plain or boring. It’s comfortable, fits well and certainly feels like it’ll last longer than most high street bras. Available in a variety of colours and up to an F cup.
Aerie Bridget Push Up Bra: £26.95, American Eagle Outfitters
With a little push-up and padding for extra lift, this bra is great for giving you a slight boost. The lace trim and straps are beautiful, but could potentially limit what you can wear over the top. That said, showing a little lacy strap can – in the right circumstances – look chic and just a little bit sexy. With a little tassel on the bridge, this bra has more going on than most T-shirt bras but still lies smooth under clothing. Double-hooks at the back make you feel secure too. Available in four colours.
Boux Avenue Multiway Boost Plunge Bra: £24, Boux Avenue
Although it’s plain in design, this silky smooth bra is seamless and very comfortable. It’s slightly push-up, so great for providing some extra oomph to your cleavage and comes in three different colours. But what’s most useful about this bra is the adaptable straps – they can easily be crossed over to fit under racer back tops or turned into a halterneck.
The Verdict: Best T-shirt bras
For its incredible comfort and classic but pretty design, not to mention its affordability, the M&S bra takes first place. We recommend getting one in every colour.

The reality of bra shopping: You find a cute style you love—perhaps a convertible racerback or a demi-cup with lace detailing—and you snap it up to try on at home. The bra looks perfect until you pull that white T-shirt over your head…then it’s a disaster. You can see the outline of the cups against your maybe-too-thin-but-very-comfortable shirt, the sliders on your bra straps leave bumpy marks underneath, and the underwire is just too obvious. The struggle, I know. Finding the perfect bra to wear under a white T-shirt requires patience and perhaps a few annoying store returns.
In an effort to save everyone some time and stress, Marie Claire decided to put a bunch of bras to the test, hoping to once and for all find a style that will always look great under a white tee. We conducted an exhaustive search for T-shirt bra options (defined as a mid-coverage style that provides support but looks seamless under your clothing) from giant retailers like Target and Nordstrom and direct-to-consumer brands like ThirdLove and CUUP, in addition to tapping our friends and coworkers for their favorites. Then we ruled out designs with lace and exuberant prints, instead sticking to neutrals to minimize the bra’s visibility.
Once we narrowed down the brands we loved, we hit a vexing roadblock: Very few brands offered T-shirt bras in a range of color and sizes that accommodated our six volunteers. That should be less and less of a problem going forward, though; many retailers are working hard to accommodate chests of all sizes and women of all shades as the calls for lingerie companies to become more inclusive have never been louder.
With all this—availability, price, and popularity—in mind, we landed on five brands to test: Cosabella, CUUP, Knix, Harper Wilde, and Lively. Then, six women, all with varying bust sizes, tried on the same bra style from each brand under a soft, flattering, and not totally sheer Banana Republic crew neck tee ($20). Each woman crowned a favorite bra, followed by a runner up.
Your journey to the perfect white T-shirt bra ends here.

Why It Won:
“When I look for a bra, it’s important that it supports and lifts my small boobs. This one hugged me just right and I liked the crisscross design in the middle. I prefer bras with underwire, and this bra has one under its buttery-soft fabric. It also has this v-neck shaped cup, so I could wear a low-cut T-shirt with this if I wanted to.”
The Runner Up: CUUP
“I liked CUUP a lot because it felt like you weren’t wearing a bra. But it didn’t give me as much of a lift as the Harper Wilde one.”
The Demi CUUP shopcuup.com $68.00
“When you slip this one on, it feels like you’re not wearing a bra. And I am the type that doesn’t like wearing bras. The cups are a little sheer, which gives it that sexy yet cute vibe. There are no harsh lines when you wear it under a tee and it fits well. I usually only wear bralettes, but if I had to pick a bra, I would wear something like this.”
The Runner Up: Harper Wilde
“I feel like both bras are very similar. Harper Wilde was comfortable too, but it was a little thicker than CUUP.”
Evolution Demi Bra Cosabella cosabella.com $74.50
“The Cosabella bra is so comfortable and makes everything look and feel great. The cups are not push ups, which I like, and have a very snug fit. I have a long torso, and I feel like this bra breaks up my frame and it doesn’t cover up my chest completely. I normally only wear sports bras, so I am surprised this one fits as well as those and has the same level of comfort.”
The Runner Up: Wiley
“It was soft, but it’s a little more covered. I like the finishing of the cups for something a little different.”
The Demi CUUP shopcuup.com $68.00
“This bra had the most natural fit on my boobs and I don’t feel like I’m wearing a bra at all. The material is a little see-through, and this sheer quality reminds me of my favorite bralettes, which I usually wear. I actually saw this brand featured on Instagram and wanted to try it on, so I’m glad I had the chance. I love it.”
“This bra fits so naturally, you don’t feel it. It also gives you support where you need it.”
The All-Day Deep V No-Wire Lively wearlively.com $35.00
“When I look for a bra, I generally shoot for comfort first because you’re going to be wearing it all day. I pay attention to how the cups fit my boobs and the design of the bra, too. This one is soft to the touch and I didn’t feel any press on my chest—like it was squishing my boobs in. I am surprised it doesn’t have an underwire because my boobs still feel fully supported. The quality for that price is really good too.”
The Runner Up: CUUP
“I like this one because it’s light and airy. I didn’t feel any pressure on my chest and it was super soft.”
Padded V-Neck Bra Knix $55
“This one wins in overall comfort and the way it gives my breasts a lift. It doesn’t squeeze anything. I usually wear wired push up bras, so this is a whole other experience. This is so comfortable, I might have to switch from my other bras. I can even see myself working out during the day in this versus the other bras, which I would only wear for a few hours if I had to.”
The Runner Up: Cosabella
“This bra was comfortable and gave my breasts a lift, but Knix was slightly comfier.”
