You don’t have to worry about bra straps showing when they don’t exist, and these lace bandeau bras are comfortable enough to wear all day. They’re unpadded but lined with a soft modal blend for a skin-friendly finish and have small loops inside for attaching your own straps when you need them. The wide band’s elastic bottom wraps around like a hug to stay in place when you’re going through the motions. “Better than expected for sure!” one shopper reported. “I got these to use as a bra kinda on a lazy day or under tank tops or wearing around the house and they’re super cute, soft, and comfortable!”

For a seamless option, try this padded bandeau bra in sizes up to 8X.

One reviewer wrote: “I ordered this two days ago and it came on time and I tried one on to see how it fits and it fits perfect. It’s stretchy and soft and yes, it is true to size. Thank you because I needed this with some of the tank tops that I own.”

Even if these bralettes happen to show, you might think they’re part of your tank since they blend in so well. Their delicate straps are thinner than most, and the ribbed knit almost looks like a second top. The removable padded inserts are easy to remove and reinsert— just make sure the textured side is facing inward after a wash.

One reviewer wrote: “I had pretty moderate expectations about how these would fit and look when I ordered them, but when I received them and tried one on I was blown away. [...] The padding is just enough and the material doesn’t give too much when it stretches. I’ve worn one to sleep and continued to wear it throughout the next day and it’s perfectly in place. Also was comfortable to sleep in. These are great for under tank tops and T-shirts I’m so happy I discovered them. The colors are exactly as advertised.”

Absolutely a staple worth having on-hand, the Calvin Klein T-shirt bra is made from soft microfiber with ultra-thin edges on memory foam cups — yes, really — and seamless bonded edges that will disappear under clingy knit tops. (Just like your go-to seamless thong.) “I also like how petite the straps are,” one shopper described, adding that “they’re very dainty” and “they hide well under most tanks in the summer.” And many reviewers reported having owned theirs for years because they were that well-made.

If you’re shopping on a budget, the Amazon Essentials T-shirt bra is a worthy alternative with a similar invisible finish.

One reviewer wrote: “I really like this bra because it’s adequately lined but not padded, provides full coverage, and is very comfortable. It’s the perfect t-shirt bra for me.”

I’m still counting the number of ways this convertible bra can be worn (at least eight!). From halter tops to one-shoulder pieces, this bra is ready to be reconfigured to disappear underneath the most striking statement tops, no matter how many improbable cutouts they have. Inside the molded cups you’ll find two angled push-up pads with a sturdy underwire, and the band features a border of nonslip mesh (plus three rows of hooks and eyes) for extra support. One shopper summarized: “If you're looking for the perfect strapless bra, this is the one.”

For even more strap options that work with dramatic necklines, this convertible plunge bra from a different brand has a second band that accommodates backless tops.

One reviewer wrote: “This is exactly what I needed in a strapless bra and the strap options have been an added bonus for tanks and razorbacks. There is no movement when it’s strapless and provided great padding.”

This cute bralette is one you won’t mind showing, and since it comes in 9 beautiful colors, you’ll have no problem finding one that sparks joy. It pairs a V-neckline with extra wide straps and a full-coverage racerback in scalloped lace. Plus, the soft breathable lining feels as light as air. “This is just what I was looking for,” proclaimed one reviewer. “It is very stretchy and soft. It does not bunch up or roll up and is not tight around the elastic. The inside is lightly lined with cotton. This is a perfect bra for wearing with summer dresses, and would even be comfortable enough to sleep in.”

If you’d like the option to completely hide your bra, this convertible lace bralette has thinner straps and Swiss army knife capabilities. For more show-it-off impact, try this strappy bralette with a criss-cross front.

One reviewer wrote: “I like it a lot. It's comfortable, flattering, the material is soft, it fits well. It’s not padded, though. Just something to keep in mind if you are looking for padding, then this one would not be for you. I don’t mind that it’s not padded, it still works perfect for my needs. I intend to use it with dresses and tops that are too revealing at the bosom. I read some reviews that say it’s too big and to size down, but I didn’t find that to be the case at all. I am 36C and ordered a large. For me, the fit was true to size. I ordered 3 more colors.”

It’s not a shelf bra — this tank top with a built-in bra gives you actual support coupled with light shaping all in one garment. The foam cups are fused to a sheath of soft fabric and elastic shelf, and they can’t be removed so you’ll never lose one in the wash. The tank itself, meanwhile, is supremely comfortable in a thin-yet-buttery viscose blend that feels like pajamas. One reviewer wrote: “I absolutely love these shirts. Great for the summer time. Built-in bra is so comfortable and offers good support.” It comes in an assortment of neutral and brighter hues and is also available in packs of two or three for a few more dollars.

For a more streamlined strap, the Hanes cotton cami has a classic fabric shelf bra and adjustable straps. (Not to mention over 24,700 Amazon ratings.)

One reviewer wrote: “I have seen adds for bra alternatives but didn’t buy any because I didn't want to be disappointed. A friend recommended these [...] The fabric is stretchy and feels nice against my skin. I tuck them into my pants and they stay put all day, don’t roll or bunch. I wash them in a mesh bag and hang dry.”

They’re the best nipple covers on the market for several very good reasons. The medical-grade silicone has a matte finish that won’t bounce back in flash photography, with a seamless edge that tapers down to nothing for a second-skin look. They come in five colors and two sizes with options for adhesive and adhesive-free coverage that everyone can wear. “This is probably one of the best purchases I’ve ever made on Amazon,” a shopper swore. “Just press them on and BAM, they are covering you up the entire day/night. They are also super easy to clean — you just use warm water and hand soap and let them dry. The case they come in is great too because it allows you to keep them separated and they’re super easy to travel with.” Best of all? They boast an impressive overall rating of 4.7 stars after more than 21,000 reviews.

One reviewer wrote: “These things are truly amazing. I got another pair because I use them so often. I tried other brands but you can still see the nipples through them. I can wear these with a white tank and it looks flawless! I wear them all day long and they don’t come off.”
