Strapless bras have a reputation for being the worstâand for years, I agreed. Every single one I owned gaped at the top, dug into my ribs, or slid down the second I moved. Still, I wore them anyway, tugging and adjusting my way through weddings and special events because I didnât think a better option existed.
Earlier this year, I set out on a mission to finally find a strapless bra that actually lived up to its promises. And while I discovered a few solid contenders, the fall weddings and holiday parties on my calendar felt like the perfect excuse to test a few more. Since the last update to this story, Iâve evaluated four additional styles for a total of 17 overall.
After wearing them with everything from formal gowns to sleek tops, the SpanxSmooth Suit Your Fancy Strapless Bra remains my top pick. Itâs lightly compressive, actually stays put, and gives a smooth, lifted shapeâsomething I especially appreciate as a mom of four approaching 40. Of course, the perfect bra looks different for everyone, so I also asked fellow Glamour editors, stylists, and trusted friends to share their go-to strapless bras, from everyday options for both small and large breasts to strapless push-up styles you wonât want to rip off right away.
We researched the market for the most popular and well-reviewed strapless bras from brands both big and small, plus asked stylists which ones they recommend to their clients and even use themselves. Then I tried the most widely recommended styles, plus tapped other editors with different body types to weigh in on the ones they love and rely on.
Over the course of five months, I tested a total of 17 styles. I considered the design of each bra. What kind of materials was it made of? Was it a wire bra or wireless? I also considered other features like molded cups and padding, as well as the profile. Could I wear it under a plunging dress, or was it better suited for more standard garments like tube tops and tanks with spaghetti straps? Of course, I also assessed long-term comfort and, perhaps most importantly, how well each bra stayed up. Because, well, itâs just not cute to constantly be hiking up your bra while youâre trying to tear up the dance floor at a weddingâwhoâs with me?
Weâre confident the final list contains only the best strapless bras on the market. These are the bras that feel like a second skin (read: donât dig in), sit seamlessly under clothing (no awkward shelf), and wonât require constant tugging (phew!).
Best Overall: Spanx SpanxSmooth Suit Your Fancy Strapless Bra

What we love: Ample silicone grippers to help the bra stay up; breathable and quick-drying fabric; cups provide a very natural and desirable shape
What could improve: Itâs not convertible
Spanx may not be my favorite brand of shapewear, but I was seriously impressed with the strapless bra. The material is really smooth and doesnât cinch, crease, or dig. Instead, the soft fabric sits flush to create a naturally beautiful shape, thanks to light compression. There was no shelf, nor were there any lines in sightâeven while wearing thin, tight bodysuit tanks. The fabric is also breathable and quick-drying.
Importantly, this strapless bra has serious staying power. There are more silicone strips on the wings than any other brand I tested, and silicone dots on the top of the cups to further aid in the no-slip department and help minimize any gaping issues. I successfully made it through a day in which I logged more than four miles walking in the city without adjustments and even spent a few hours dancing one evening with only minor adjustments. For all of that staying power, there is one concession to be made: It doesnât have convertible straps, so you can only wear it as a strapless. (PS: If you wanna save some coins, peep these Spanx promo codes.)
Best for Large Busts: ThirdLove 24/7 Classic Strapless Bra
ThirdLove 24/7 Classic Strapless Bra
Original video from Brigitt Earley testing ThirdLove 247 Classic Strapless Bra
What we love: Inclusive sizing; poke-free flexible underwire; supportive memory-foam cups; includes clear and matching-color removable straps
What could improve: Some reviewers report inconsistent sizing
Get some good grip and full coverage with ThirdLoveâs classic bra. Glamour reviewer Emily Rodriguez praises this braâs comfort. âI wore this strapless bra all day, and (a) it stayed in place, but (b) it didnât make me feel like I was constricted by intense underwire,â she says.
I had a similar experience with this option but did find it ran a bit small. Even the cups looked and felt smaller than some other brands I tried, which may make this a better pick for those with small chests. The underwire didnât dig in but offered a nice little lift. I also appreciated the shape of the molded cupsâthey arenât too padded yet add some shape. The garment sat nice and flush with my skin, too, so I didnât experience that awkward shelf you often get with other strapless brasâgreat for clean lines under your favorite tee.
