A Straightforward Guide to the Best Strapless Bras That Actually Stay Put
With the help of experts and first-hand testers, we've brought you the best size-inclusive, no-slip bras for your summer wardrobe.
As many women know all too well, finding the best strapless bras can be a frustrating experience. I went through years of trial and error, tormented by faulty strapless bras that slipped down around my sides and caused awkward cup gapping. These bras were so aggravating that I avoided warm-weather pieces that required them all together, like tube tops and strapless summer dresses.
Nowadays, I have finally built a collection of strapless bras that I can rely on for all my wardrobe needs, and I’m here to help you do the same. I’ve consulted two leading experts in the bra industry—ThirdLove's co-founder Ra'el Cohen and Spanx’s Vice President of Innovation and Design Wendy Hanson—to discuss mastering the art of strapless bra shopping.
“First of all, understanding your breast shape and size is crucial,” says Cohen. “Less coverage tends to work best for petite frames while more coverage and wider hooks accommodate larger busts,” she adds. The bra connoisseur also tells me that bras lined with no-slip silicone strips offer the most reliable support.
As for which features to avoid, Hanson mentions that shoppers should steer clear of strapless bras with rigid cups and wires. “These types of bras lack the flexibility needed for a comfortable fit, and they can ultimately cause unwanted irritation,” she says.
Keep scrolling for more insightful tips from Cohen and Hanson and a cohesive edit of the best strapless bras on the market. The list ahead features a variety of bra brands that I've either tested for myself or extensively researched, so you can rest assured that these strapless bras will give you the support you need (pun fully intended).

While scouring the internet for the best strapless bras for women with large busts, I kept coming across Curvy Couture (an inclusive lingerie brand that offers a variety of size options ranging from 32B to 46J). Curvy Couture's strapless bra is made with smooth microfiber cups, a stay-put silicone lining, and a cushioned lower band for extra support. “I'm a size 34G and this strapless bra feels so secure—I never have to adjust it,” one reviewer wrote. “It holds up my 40Hs without digging or poking, and it’s so comfortable that sometimes I forget I'm wearing it,” said another.
Sizes: 38C-44H (5D)
Color: Black
If you have small busts, you've likely experienced cup gapping, which is often caused by extra space around the top of the bra. Lucky for you, I have a solution that can fix your bra problems. Pepper specifically makes bras for women with small bust sizes (between 30AA to 40B). The brand's MVP Multiway bra, is intentionally designed with balconette cups, which are shallow cups that create fullness on the top of the breasts. “I ordered a 36AA and I didn't experience any gapping or slipping, the fit was perfect,” said a reviewer.
Sizes: 30AA-40B
Colors: Ecru, sand, buff, sienna rose, fawn, wood rose, tuscan, espresso, black
This Spanx strapless bra is my latest lingerie purchase, and I’ve been wearing it nonstop. My favorite part about this bra is that it doesn’t budge during the day, no matter how much I move around. It’s equipped with a silicone strip placed along the back lining of the band, which ensures ample stability. The band doesn’t cause any digging, meaning I can wear this cozy bra all day without any discomfort.
Sizes: 32B-38DD
Colors: Black, beige
I own several pieces from ThirdLove (including their cult-favorite T-shirt bra and Classic Bikini Swim Set), so I had to try the brand’s strapless bra. After slipping it on, I was impressed by how the foam cups and no-slip silicone grips held everything in place. I would specifically recommend ThirdLove’s strapless bra to those between sizes, as their designs feature half-cup sizing that caters to various sizes.
Sizes: 32AA-44H
Colors: Taupe, black
If you’re looking for a bra with a barely-there feel, Fleur du Mal offers just that with their strapless bandeau bra. It's snug without feeling constricting, likely due to the flexible blend of polyamide and elastane. Aside from appreciating how this bra comfortably molds around my chest, I love how it looks. The sweetheart neckline and gorgeous lace trim along the back make this bra stand out from the rest.
Sizes: XS-L
Colors: Tan, black
Other Strapless Bras We Love
This Skims strapless push-up bra provides support for those days when I need a little lift. While many of the push-up bras that I’ve tested in the past have unbearable rigid wires, Skims’ bra features a cushioned underwire that doesn't dig or pinch. The foam padsa also creates an enhanced look without causing any spillage.
Sizes: 30A-44F
Colors: Sand, clay, sienna, bronze, jasper, cocoa, onyx
Else’s lace bra is a multipurpose masterpiece; by that, I mean you can wear it in more ways than one. I wear it as a regular strapless bra for practical purposes when I want an airy feel (the delicate fabric is extremely breathable). On the other hand, sometimes I’ll style this dainty number as an extra layer beneath a plunging blazer for a night out. The lace adds a pop of dimension that can effortlessly elevate any going-out outfit.
Sizes: 30C-38DD
Colors: Ivory, black
After reading countless reviews on Savage X Fenty’s site, it was obvious that women are obsessed with the brand's strapless bra because of its soft texture.
“I love this bra because the material is buttery soft,” one reviewer wrote about Savage X Fenty's Core Microfiber bra. “This bra is literally my second skin,” said another satisfied customer.
The style is cut from a high-shine microfiber material made of polyamide and elastane, specifically intended to have a soft-to-touch effect.

Colors: Brown sugar nude, honey nude
Wacoal’s Red Carpet bra earned its name for a reason—it's designed to wear under a strapless gown. "I absolutely love the feel of this bra and it fits perfectly beneath my dress,” wrote one Wacoal customer. With silicone strips along the top and bottom edges, you won’t have to worry about constantly reaching into your dress to pull up your bra. Plus, Wacoal’s strapless bra is crafted from a seamless nylon fabric that minimizes bulging, so your dress will look flawless from the outside.
Sizes: 30B-44H
Colors: Roebuck, sand, black, brush
When you want to show off a top (or a dress) with a deep neckline, you can count on Cosabella’s Never Say Never Plungie bra. This bra is constructed with a low-cut front, lightly lined cups, and silicone non-slip grips that will keep the bra secure. According to one reviewer, this piece is essential for anyone seeking all-day comfort: “This plunge bra is the first strapless bra that has stayed put, and not just for a couple of hours, but for an entire day.”
Sizes: 30C-36F
Colors: Black, tan, red
The styling options are simply endless with Victoria’s Secret’s strapless bra. Thanks to its adjustable straps, this piece can be worn in five ways (yes, five!) to work with what you're wearing. Strapless, classic, halter, cross back, or one-strap—you name it! A reviewer even wrote that this bra is so versatile that she “never has to wear another bra again.” Another agreed, saying, "It’s the only bra I have owned in the last eight years."
Sizes: 30A-44G
Colors: Black, caramel, praline, toffee, white, marzipan, ganache, mousse
If you’re on a budget, but you’re still looking for an effective bra that will get the job done, consider Cupshe’s strapless bra.

"I wore this bra while attending a beach party and felt comfortable, confident, and carefree,” she added.
Sizes: XS-L
Colors: Beige, black, neutral
What To Look for in the Best Strapless Bras
- Shape and Size
As Cohen mentioned, you should assess your bust size before embarking on your strapless bra-buying journey. If you lack confidence in your measuring skills, head to a local department store or lingerie boutique for a professional measurement. Once you’ve checked that off your list, you can begin to understand what type of cups and bands work best for your busts.
“Those with larger busts should prioritize snug strapless bras that offer more coverage,” says Cohen. In this case, opt for a bra with tall wings and deep cups. However, bras with larger surface areas should promote a supportive fit without being too heavy. “Thick padding can add unnecessary weight and pressure, so you’ll want to choose a lightweight style that is engineered to stay in place,” adds Hanson.
If your breasts are smaller, Cohen recommends strapless bras with “lightly padded foam cups that help to lift and shape.” Hanson also agrees, noting that this feature can “subtly enhance volume in a natural-looking way.”
- No-Slip Lining
“A comfortable strapless bra should have a no-slip back strip made with silicone technology,” Hanson tells Marie Claire. She shares that shoppers should also consider a strapless bra featuring silicone inside its cups. “Silicone along the top of the cup can keep the bra securely in place,” she notes.
Although your strapless bra of choice should remain sturdy with the help of silicone, it shouldn’t poke at your skin. With this in mind, Hanson recommends avoiding “digging elastic trims” that can cause “significant discomfort.” Instead, go for a design with a smooth, dig-free lining that stays put without irritating your skin.
- Adjustable Hooks
Unless you’re searching for a stretchy bandeau bra with a slip-on feature, your strapless bra should have more than one hook along the back closure. “This type of adaptable feature ensures a custom fit," explains Hanson. "Strapless bras without hooks can’t be tailored to fit your unique shape, leading to poor support.”
- Breathable Fabrics:
“Seek out bras crafted from quick-drying, breathable fabrics for comfort, particularly as outdoor temperatures rise,” says Hanson. Strapless bras cut from fabrics like cotton, nylon, soft lace, and even mesh are typically your best bet.
