No Big Deal, I Just Fulfilled My Life’s Purpose and Found 10 Strapless Bras That Don’t Ruin My Life

Over the years, Cosmo readers have consistently crowned this one their all-time favorite—so of course, it earns the top spot on our list. The convertible strapless bra, featuring cushioned underwire, was designed to feel as comfortable (and invisible) as possible. Thanks to the no-slip elastic bands, it actually stays put—no sliding, no constant adjusting. And let’s talk about the full-coverage cups: They keep everything exactly where it should be, offering support and security. It’s called the This Is Not A Bra for a reason! That said, some longtime fans have noticed changes in sizing over the years. Some say it runs small and recommend sizing up one size. Still, the fact that people keep coming back? That kind of loyalty speaks volumes.

It’s a go-to favorite for delivering 10/10 performance in all the key areas: support, softness, stretch, breathability, and lightweight comfort. From the lightly molded cups to the stay-in-place silicone tape along the neckline, every detail is designed to keep you feeling secure and confident all day long. One reviewer even said the support is so good, it’s helped alleviate back and shoulder pain!

I’ll always stand by the belief that the best bra is the one that feels the least like a bra—so a bandeau style isn’t just comfortable, it’s the ultimate go-to for those strapless moments. This one has no wiring, features ultra-soft 4-way stretch fabric wrapped snugly around your chest, and removable padding that makes contour and shape totally optional. Plus, its smooth silhouette practically disappears under your clothes!

Jayne Lemire, executive assistant, who wears a 34B cup: “As someone who hates wired bras, finding a strapless bra that gave support, stayed put, and was comfortable was a herculean task. Aerie’s Smootheez bralette is the only one I’ve found that does all three! It also comes in a variety of colors and has detachable straps just in case.”

In my experience, going strapless usually means giving up on lift. But the Very Sexy Push-Up Strapless Bra from none other than Victoria’s Secret? Lift is a priority. The ultra-comfy, supportive padding (which adds up to a full cup size—my 32A boobs are rejoicing) combined with the V-shaped cutout and grippy, stay-put band, is the secret sauce for getting the girls up and staying up.

Tamara Fuentes, entertainment editor, wears a size 36D bra: “One thing that I love about this bra is that while this is marketed as a strapless, it does come with straps that allow you to use it in any way. It gives you such a great lift without digging into your skin and can stay up all on its own all day. My biggest issue with most other strapless bras is the constant need to pull them up, but this one stays put no matter what! Unlike most push-up bras, the lining on this is very comfortable and won’t dig into your skin, making it perfect to wear all day. Out of all my VS bras, it truly is the one that I keep coming back to.”

If you ask me, a plunging strapless bra is a total wardrobe essential. It’s the go-to fix when the chicken cutlets just aren’t cutting it and you need real support. The U-shaped plunge on this one is ideal for those low-cut looks, so you’re not stuck choosing between going bare-chested or skipping the cute, flirty dress altogether. Plus, the push-up padding wraps all the way around, giving you lift and security from every angle

Another Cosmo reader fave, this top-rated bra is a go-to for its flawless, sculpted fit.

No itty bitty titty gets left behind on Pepper’s watch! This brand is all about giving small boobs the support they deserve—and yes, that includes a strapless bra that actually stays up (even if you feel like you’ve got next to nothing). It even features a balconette style that gives a natural-looking, rounded lift without trying too hard.

Hannah Oh, shopping editor, wears a 30B: “I wore this under a bridesmaid dress and didn’t think about it once—which is saying a lot, because a bad bra will totally hijack your mental space. Is it slipping? Is it showing? Does it look weird if I shift how I’m standing? The Pepper Strapless Bra has carried me through weddings, dates, and office days. I have a small ribcage, so I love that it goes down to a size 30. All the support comes from the band, which I need to fit snug around my torso—it also prevents that weird gaping at the top of the cup I sometimes get with strapless bras.”

Even with what feels like hundreds of strapless bras out there, finding one that actually comes in a wide range of sizes is still like searching for a needle in a haystack. But that’s definitely not the case with Lane Bryant—especially when it comes to their Comfort Bliss Bra. Designed with an inclusive size range in mind, it offers full coverage and legit support thanks to its molded cups and wide band while still feeling light as a feather and super breathable.

Olivia Truffaut-Wong, news editor, wears a 42C: “Let’s just say, I have multiple versions of this Comfort Bliss multi-way strapless bra from Lane Bryant. This bra gives me shape without discomfort and never falls during the day, keeping me looking nice and lifted. There is boning on the side, but if you get the right size, it shouldn’t irritate because it really maintains its shape throughout the day—no pointy edges or bends! I can wear this bra for 12 hours plus without feeling the desperate need to take it off, which many of you know is a miracle in and of itself.”

With over 6,000 glowing reviews and a near five-star rating, this bra really doesn’t need much of an introduction. It’s a great pick if you’re looking for a more stylish strapless option that stays smooth and invisible under clothes, but still cute enough to peek out from under a loose blouse or something sheer. Bonus points for its trifecta of support: underwire, side boning, and a silicone grip along the top edge so nothing moves out of place.

Silicone strapless bras are always my go-to. Dealing with straps digging into my skin is literally my 13th reason. And this self-adhesive option feels almost imperceptible. You can wear it with almost anything—whether you’re heading to work, out on a date, or grabbing dinner with friends—and it keeps everything in place without showing that you’re even wearing a bra. I especially love that it uses medical-grade adhesive and features a soft fabric lining, making it extremely gentle on the skin.

Tamara Fuentes, entertainment editor, wears a size 36D bra: “I’m not exaggerating when I say that this bra is my secret weapon. Not only has it held up in all kinds of weather, but the fact that you can easily adjust it to give you the lift that you’d like is a godsend, as it makes it easy to wear with anything. While the adhesive actually takes a while to dry, you can easily wash it with a special solution to bring it back to normal. I’ve worn it through long days, and it’s always been super comfortable.”
