The best T-shirt bras are the ones that make us forget weâre even wearing anything at all. To help you find the best ones for your cup size, we did the heavy lifting (literally and figuratively) of testing a wide range of options on different body typesâfrom small busts to fuller chests and everything in between. Whether you like molded cups, convertible straps, or breathable fabric for hot summer days, these picks passed our wear tests under everything from white T-shirts to clingy tanks. Most of them were undetectable under our favorite tank tops.

ThirdLove 24/7 Classic T-Shirt Bra
Who itâs best for: Anyone looking for an everyday bra that offers all-day comfort and support, especially if youâve struggled to find your true fit or land between standard cup sizes
This bra combines a smooth, lightly padded design with premium details like memory foam cups that mold to your shape and half-cup sizing for a more precise fit that feels tailored, supportive, and surprisingly comfortable. The adjustable straps are designed to stay in place without slipping, and the lingerie brand is known for their soft but sturdy balance of stretch and structure.
During testing, I was particularly impressed by how soft and comfortable the straps felt throughout the day. And I love that thereâs underwire for a little lift, but absolutely no digging, In fact, I was so drawn to this bra that I ordered the new TempSync version for summer. Itâs made with a patent-pending cooling fabric to help balance body temperature on hot days (itâs also marketed to those going through menopause, according to the brand).
What we love: Half-cup sizes for a more custom fit; comfortable straps and underwire; comes in a variety of colors, as well as lace options
What could improve: May not be full-coverage enough for larger busts

Aerie Smoothez Full Coverage Lightly Lined Bra
Who itâs best for: Anyone who wants maximum comfort without giving up support. Ideal for small to medium busts.
This bra is a standout for its barely-there feel and second-skin fit that moves with you. Itâs made with a soft blend of nylon and elastane that feels smooth to the touch and looks completely seamless under clothesâeven tight T-shirts or tanks. Thereâs no sacrificing shape, either, thanks to lightly lined, full-coverage cups and a flexible underwire that offers gentle support without digging.
One of our testers who usually avoids underwire at all costs said this bra made her rethink everything. âItâs so soft and seamless, I almost didnât notice it had underwire,â she said. âDefinitely a new favorite.â Bonus: The flat hardware and four-row hook-and-eye closure offer just the right amount of customization, so you can dial in on the right fit and support.
What we love: Supersoft, seamless design that disappears under clothes; flexible underwire for all-day comfort; smoothing wings for a sleeker fit
What could improve: Straps are not convertible
Available sizes: 32Aâ42DMaterials: 80% nylon, 20% spandexColors: 15 optionsBest Demi: Cuup The Demi SpacerOriginal photo from Brigitt Earley testing Cuup The Demi
Who itâs best for: Those who want a lightweight, breathable bra with plenty of support
Made with a lightweight 3D spacer fabric, this bra is known for its exceptional breathability, making it a perfect choice for warmer weather or anyone who tends to sweat more. The lightly lined cups offer a natural shape with a barely-there feel, while a flexible underwire provides just the right amount of lift and support without sacrificing comfort.
I usually gravitate toward bralettes for that lightweight feel, but I thought this was one of the more comfortable bras I tried. I especially liked that it has three rows of hook-and-eye closures for extra support and itâs barely noticeable under T-shirts. On the downside, I did notice the band stretched out a bit over time, but Iâm not especially gentle when washing my delicates.
What we love: Breathable, lightweight fabric is ideal for warm weather; comfortable underwire; wide range of sizes
What could improve: Band stretched out over time

Victoria’s Secret Cotton Lightly Lined Full-Coverage Bra
Who itâs best for: Those who want a breathable, comfortable full-coverage bra thatâs perfect for everyday wear, especially in warmer climates
This bra is perfect for days when you want to feel snug and secureâbut like youâre wearing nothing more than your favorite tee. Itâs made from a soft cotton-modal blend and has lightly lined cups that offer just enough coverage while staying lightweight and breathable. The flexible underwire adds a bit of support without digging in, and the smooth, breathable fabric helps keep you cool in hot, humid weather.
I really appreciated how soft it felt against my skin, while still feeling much more secure than your average bralette. I wore it during a few marathon errand days in peak summer heat and never once felt restricted or needed to make adjustments.
What we love: Breathable cotton-modal blend; flexible underwire; lightly lined cups; tons of color options
What could improve: Doesnât offer as much overall support as some options

Wacoal Women’s Basic Beauty Contour T-Shirt Bra
Who itâs best for: Anyone who wants molded support, full coverage, and a bra that stays put. Ideal for those with larger busts.
For those who want molded cups, this best-selling bra from Wacoal features contoured, full-coverage cups that shape and support while preventing spillage and avoiding adding bulk. The wide, camisole-style straps are fully adjustable, and the three rows of hook-and-eye closures help ensure a secure, supportive fit, especially for larger or sagging breasts.
I ordered my usual sizeâa 32Dâand the cups fit perfectly, feeling smooth and supportive throughout the day. Just note: This is true full coverage, so itâs better suited for crew-neck T-shirts than V-necks or tanks. That said, you can move around without anything shifting out of place. Also of note: The lining is minimal, so there may be some nipple show-through or a desire for more shaping, but I personally appreciated the breathability on warm days.
What we love: Full-coverage cups that prevent spillage in larger breasts; wide, supportive straps that donât dig in; lightweight and breathable
What could improve: Sizes are limited for those with smaller chests

Calvin Klein Triangle Wireless Bralette
Who itâs best for: Anyone looking for a wireless bralette with real support. Ideal for those with small to medium busts.
Made from soft cotton with a wide, supportive elastic band, this bralette-style T-shirt bra offers just enough structure to keep everything in place, whether youâre lounging, layering under a tee, or just wearing it by itself. The racerback straps provide extra support and a secure fit, while the plunging neckline makes it more versatile than youâd expect from a full-coverage bralette.
âIâve been more conscious about bra comfort after I was diagnosed with a fibroadenoma (a noncancerous tumor) in my right breast, so Iâve been reliant on this bra since then,â says Glamour commerce writer Alanna Martine Kilkeary. âItâs wildly comfortable, isnât too tight at the band, and gives me enough support without squeezing my boobs.â
Glamour commerce editor Malia Griggs added, âEven though it doesnât have underwire, this Amazon bra provides just the right amount of support for my 32D boobs, thanks to its thick supportive under-bust band. Its plunging shape is flattering and low enough to wear under trickier outfits, and its bands are thick enough to provide some back support.â
What we love: Supersoft cotton design; racerback straps for more lift and support; flattering plunge that works under trickier necklines
What could improve: Logo band can show under thin or light-colored tops

Evelyn & Bobbie Starlujoplette Plunge Bra
Who itâs best for: Anyone looking for a wireless bra that sculpts and supports while remaining invisible under T-shirts and tanks
This wireless and seamless bra is proof you donât need an underwire to feel lifted and supported. Itâs made from soft, stretchy fabric that hugs your body and moves with you, while keeping everything securely in placeâespecially along the sides and under the bust. The plunge neckline isnât quite as low as some other options, but the slim straps and ultra-smooth, seamless construction help it disappear under even the clingiest T-shirts.
Iâve had mine for over a year, and it still offers the same level of support as it did on day one, which is saying something for a wireless braâespecially since Iâm not exactly precise when it comes to laundering my undergarments. It does feel snug at first, but as the brand suggests, it gradually molds to your shape without stretching out or losing its structure. The side support is worth calling out too. Iâve found the smoothing panels do an excellent job at keeping everything contained and bulge-free.
What we love: Seamless cups with soft edges donât show through clingy tops; fabric molds to your body over time without losing structure; suitable for both smaller and larger chests
What could improve: Plunge isnât as low as some may want for deep-cut tops
Available sizes: 30â44 DâJ (based on Evelyn & Bobbieâs size chart)Materials: 62% nylon, 38% elastaneColors: Core shades like Sand, Mica, Clay, Umber, and Black, plus rotating seasonal colorsBest Sports Bra: Alo Airlift Intrigue BraOriginal photo from Brigitt Earley testing Alo Airlift Intrigue Bra

Alo Airlift Intrigue Bra
Who itâs best for: Smaller-chested individuals who want a versatile and comfortable wire-free bra that works for everything from light workouts to everyday wear
This sports bra checks all of the boxes: Itâs comfortable, supportive, and stylish enough to wear beyond the gym. Made from Aloâs signature buttery-soft Airlift fabric, it offers gentle compression with four-way stretch that moves with you whether youâre doing yoga or lifting groceries into the trunk. It has a slimmer profile than your average sports bra for a more flattering fit and comes with removable padding to help you customize the shape (I wear mine without).
Iâve had this bra for a couple of years and reach for it oftenânot just for light workouts like barre or strength-training, but also for everyday wear. Itâs especially great under racerback tanks or fitted crew-neck bodysuits. The fabric feels breathable and barely there, and even though you might see some faint lines under clingy tops, the comfort easily outweighs the pain point.
What we love: Buttery-soft fabric; highly versatile; removable padding
What could improve: Some visible lines under clingy fabrics

Spanx Spanxsmooth Suit Your Fancy Strapless Bra
Who itâs best for: Anyone who regularly wears tight tees and tanks with tricky necklines and needs a strapless bra that actually stays up
If youâre looking for a strapless bra that can double as your go-to T-shirt bra, try this option from Spanx. Itâs key for outfits where you want zero straps showing but still need smooth, seamless supportâlike under tight tees or bodysuits with trickier necklines.
What really impressed me about this one? The staying power. The bra has more silicone grippers along the wings than any other strapless bra Iâve tested (upwards of a dozen), and there are even silicone dots at the top of the cups to prevent slipping and minimize gaping. I wore it for a day packed with over four miles of walking, plus several hours of dancing, and only needed minor adjustments. The only trade-off? Itâs not convertible, so youâre committed to strapless wear.
What we love: Tons of silicone grippers and dots to keep it firmly in place; breathable, quick-drying fabric; cups provide a natural, flattering shape
What could improve: Itâs not convertible

Natori Bliss Perfection Comfort T-Shirt Bra
Who itâs best for: Anyone who wants a barely-there T-shirt bra that combines comfort, support, and a smooth, natural shape.
Iâve had this bra for longer than I care to admit (you can definitely tell when you look at it!), but I just canât bring myself to part with it because itâs that comfortable. It feels like Iâm wearing nothing at all, even though it has underwire for support and delicate lace details for style points. The lightly lined cups sit flush against my skin, making it completely invisible under T-shirts too. And thereâs no extra padding to add bulk or create a weird shape under clingier garments.
Beyond the comfort, the seamless molded design gives a natural lift (similar to a push-up bra) and smooth silhouette, making it my go-to whether Iâm running errands or dressing up. For a bra thatâs both supportive and feels barely there, itâs hard to find a more perfect fit.
What we love: Lightweight, breathable fabric that feels like a second skin; seamless cups with just the right amount of lining and coverage; both supportive and stylish
What could improve: The lace is more prone to wear than the rest of the bra

Etam Wireless Lightly-Lined Bra
Who itâs best for: Anyone looking for a wireless, lightly lined bra that stays invisible under clothes and feels weightless even in hot weather.
Etamâs wireless bra is lightly lined but doesnât have padded cups, offering a natural shape without any extra bulk. The ultra-soft microfiber fabric is breathable and comfortable enough to wear all dayâeven in hot summer weather. And, thanks to its discreet finishes and second-skin feel, it stays invisible under clothing. The cups provide medium support with a natural plunging neckline that works well under most T-shirt styles.
This bra is another go-to for Griggs, who says it checks all the right boxes: soft, cozy fabric, a wireless design, and enough support for her 32D bust. Her only complaint? The back clasp can be a bit scratchy, though she says a piece of clear tape is a quick fix to prevent irritation.
