Best in Class

The Aerie Real Sunnie Strapless Lightly Padded Bra is a perfect example of how strapless bras can combine comfort and support. We wore this strapless bra for over five hours without needing to readjust, and it kept us lifted, covered, and secure. The lightly padded cups provide full coverage, while the underwire gives an extra boost without showing through clothing.

Crafted from recycled nylon and spandex, this bra offers a luxuriously soft feel against your skin. Its slight stretch ensures it molds to your body, providing a lift to your chest. With moisture-wicking properties, it's ideal for warmer weather, keeping you comfortable and cool. Plus, it features removable and convertible straps, making it versatile for different top styles.

We noticed that the band could be a bit tight in some sizes, so it’s crucial to consult Aerie’s sizing guide and consider ordering a couple of sizes to find your perfect fit. Despite this, the snug fit isn’t uncomfortable, and in fact, the tight band helps ensure all-day support, no matter what your day holds.

Best Value

While bras can be expensive, this Maidenform option provides reliable support and coverage without breaking the bank. Made from nylon and spandex, it’s soft against the skin and features a ComfortGrip band to keep it in place all day. For added versatility, the bra includes removable straps so you can wear it in a criss-cross or halter style.

We found this bra offers excellent coverage, although it doesn’t work with a plunging neckline. However, it does provide enough coverage to avoid wardrobe mishaps. During testing, it stayed discreet under clothing—the cups remained hidden, though the side boning was slightly visible under thinner tops.

This bra may not be the most comfortable option for those with larger busts. While it offers support, the underwire caused some discomfort, digging into the chest and back during testing. The padding also felt excessive for fuller chests. However, if you have a smaller bust, the additional padding might be more suitable. While it may not be the best choice for everyday wear, it works well as a short-term option under a strapless dress for special occasions.

Best Luxury Option

With exceptional support and comfort, this bra is worth the investment. The plunge neckline and removable straps make it versatile enough to wear with nearly any top, while the silicone grips on the cup edges keep it securely in place.

During testing, this bra offered a perfect fit—comfortable and just the right level of snugness for everyday wear. The band, slightly wider than typical strapless bras, stayed put without needing adjustment. The underwired cups and side boning provided support without discomfort, while the padding added an extra lift.

Made from a soft and stretchy blend of polyamide and elastane, this bra features a delicate lace overlay on the band for added elegance. The fabric is smooth and discreet under clothing. However, the lace began to fray after washing, so hand washing is recommended. Despite this, its versatility and comfort make it a worthy purchase for those looking for a supportive and stylish low-cut bra.

Best for Maximum Support

Spanx opts for a silicone lining on the band instead of traditional elastic, ensuring the bra stays firmly in place. The brand's innovative patent-pending fabric remains smooth against your body and holds steady throughout the day, impressing us with its reliability and eliminating the need for constant adjustments.

Not only does this bra provide strong support, but it's also incredibly comfortable, crafted from a soft blend of nylon and elastane that won’t show through your clothes or create unwanted lines. Additionally, it features removable and convertible straps, making it adaptable to various top styles.

This bra includes memory foam molded cups that conform to your shape, ensuring an ideal fit. While the material adds some fullness to your bust for a more pronounced look, it may not be suited to everyone’s preference. If you’re comfortable with padded cups, this bra offers unbeatable comfort.

Top Lace Pick

Lace bras may not always seem like the most supportive option, but this stunning choice from Cosabella proves that assumption wrong. Made with delicate French lace, it offers a lavish appearance and feel, and we love the variety of bold color choices. During testing, we were pleasantly surprised by the secure fit, despite its lightweight design, and it held up wonderfully after washing.

The cups are unlined, offering good coverage, though they create a more pointed shape. With silicone strips along the edges, the band fits snugly to keep everything in place, though it could feel tight if you're between sizes.

Although supportive, this bra is best suited for special occasions or more formal attire. It was more comfortable than similar styles, but we did need to adjust it occasionally to avoid underwire discomfort. Despite this, its blend of durability, support, and elegance makes it a great choice for upgrading your strapless bra collection.

Top Plunge

The Natori Feathers Strapless Bra stays hidden under clothing, remaining discreet even under a V-neck or low-cut top. The elegant lace pattern along the band adds a touch of luxury, and the smooth mesh overlay on the cups ensures a seamless fit. During testing, it laid flat without bunching or gapping at the cups.

The band is equipped with a silicone strip along the top for extra grip, but it could have benefitted from another strip at the bottom to prevent slippage. Nevertheless, it offers excellent coverage, even for those with larger chests, making it a solid choice for wearing under a low-cut top without the worry of a wardrobe malfunction.

The cups feature a light lining, providing comfort and breathability, though they don’t offer much lift. Side boning enhances the structure of the bra, adding support. While we wish it came in a wider range of shades to better suit various skin tones, it's still an elegant and sleek option for pairing with a plunging neckline.

Size Range: 32–36, B–DDD | Materials: Nylon, spandex, polyester | Return Policy: 30 days

Best for Large Busts

The Curvy Kate Luxe Strapless Bra is engineered for larger chests with its flexible side boning, silicone lining, and structured seamed cups. This bra provides a sturdy fit, reminiscent of a corset, ensuring ample lift and support while staying securely in place.

Not only is this bra sturdy, but it also remained securely in place throughout our testing. The silicone grips along the bottom of the band offer a snug fit, while the thicker band prevents rolling or bunching. Although the firm boning and underwire provide excellent support, we found it less comfortable for long-term wear.

The cups are lined with memory foam and feature vertical seams for added lift, though they may become visible under a thin top. However, this bra provides superior coverage compared to other strapless bras we tested, offering full support for larger busts without the worry of wardrobe malfunctions.

Best for Small Busts

Pepper creates bras tailored for cup sizes AA to B, and their strapless design features shallower cups for a better fit. "It contours slightly, preventing any gaping, which is really appreciated," says Caldwell. The smooth, soft fabric lies flat against the skin without bunching underneath clothing.

This bra includes silicone strips at the top and bottom of the band to ensure it stays in place, and it also has mesh cutouts for added breathability. The thicker band provides extra support, but it might feel uncomfortable if you're not used to it. The width and full coverage can limit its compatibility with keyhole or cut-out tops.

The cups are lightly padded and conform to your body, though they don’t add much lift. If you're seeking a bra with more volume, you may want to explore options with additional padding. However, if you're looking for a reliable everyday strapless option for casual wear, this one makes an excellent wardrobe staple.

Size Range: 30–40, AA–B | Fabric Composition: Polyester, elastane | Return Policy: 30 days

Best for Full Coverage

Wacoal Red Carpet Strapless BraPHOTO: Amazon

The Wacoal Red Carpet Strapless Underwire Bra is beloved for good reason. It’s crafted with sleek, seamless fabric that remains discreet under clothing. The hidden stays along the back and sides provide added support while minimizing bulge. Additionally, it includes removable and convertible straps, so you can easily pair it with different tops.

This bra lifts and shapes the bust with cups that feature a containment panel for separation, while the padding provides lift and full coverage. It’s especially suitable for larger busts, as the larger sizes have an extra-wide band for enhanced support. Regardless of size, the band has silicone grips to prevent it from sliding down, and it maintains its shape even after extended wear.

While this Wacoal bra offers several advantages, it might not be ideal if you're between sizes, as the band and side boning can dig into your skin. You may want to try ordering a couple of different sizes to find your perfect fit.

Best Wireless

If you're not a fan of underwire bras, this wireless strapless option from Soma offers the comfort and support you need, minus the metal. Rather than a wire, it features seamless contour cups wrapped in ultra-soft brushed fabric that lifts and shapes without digging into your skin. Plus, the fabric feels smooth and soft beneath clothes.

We were impressed with how this bra provides full coverage—no matter your bust size, you won’t spill out of the cups, and the center gore stays flat against your sternum. The band is a bit wider than most, offering both comfort and support, and features body-hugging spandex instead of silicone. However, we found sizing to be a bit tricky, so if you’re between sizes, it might be best to order a few sizes to try before making your final decision.

This bra comes with removable, multi-way straps, giving you the flexibility to pair it with various styles and silhouettes. It also offers an excellent size range, from 32A to 42G. Although finding your perfect fit might require trying a few different sizes, the comfort and versatility make it worth the effort.

Best Color Variety

If you're searching for a strapless bra that blends with your skin tone, the Victoria's Secret Sexy Illusions Lightly-Lined Strapless Bra is an excellent choice. It is available in six shades, from fair to deep, for a subtle, discreet look, and its smooth, glossy fabric remains undetectable under clothing.

This bra features lightly lined cups that offer full coverage, with a band that includes silicone grips to help keep it secure. However, there was slight slipping throughout the day. The underwire and side boning, which extends higher than most bras, may take some getting used to, but once adjusted, it feels almost like you're not wearing anything at all.

We appreciated the wider band on this bra, which provides extra support, particularly for larger busts. The design also includes appealing details like rose-gold hardware on the center gore and adjustable straps, allowing you to customize the fit and style beyond just a basic strapless bra.

Size Range: 32–44, A–G | Materials: Polyamide, elastane | Return Policy: 30 days

Final Verdict

In our tests, the Aerie Real Sunnie Strapless Lightly Lined Bra stood out for providing the best lift and support. It didn’t shift, bunch, or require constant adjustments, and it fits snugly yet comfortably. If you're looking for a more budget-friendly option, the Maidenform Ultimate Stay Put Strapless Underwire Bra is a great choice, offering excellent coverage and staying in place all day.

Our Evaluation Process

In our search for the best strapless bras, we tested 15 different styles from various brands. Two testers, one with an A-D cup size and one with a DD+ cup size, wore each bra for two weeks.

After testing each bra, we assessed comfort, fit, support, quality, and adjustability. We documented our experiences and gave each bra a score out of five points in each category to evaluate its performance.

For comfort and fit, we examined how comfortable the bra was throughout a typical day, including activities like office work, social outings, and dancing. We took note of any discomfort from tags, the band, or side boning, as well as any shifting that happened during movement, and checked if the sizing was accurate.

Regarding quality, we followed our standard bra-washing routine, keeping track of any signs of wear like stretched bands or fabric damage. We also evaluated the material to see if it felt soothing on the skin or caused irritation.

In terms of adjustability, we examined features that could enhance the bra's practicality, such as removable straps, a plunging neckline, or additional rows of hooks. We also evaluated how easy it was to put on and remove the bra. By combining these observations with the ratings we gave in each category, we were able to identify the best strapless bras.

Mastering the Art of Shopping for Strapless Bras

Getting the Perfect Size and Fit

Getting the right size and fit is essential when buying a strapless bra. As Caldwell points out, 'Most people are wearing a cup size too small with a band size that’s too large. With a strapless bra, this leads to a constant struggle, and it will slip down.'

Strapless bras, like backless bras, follow the same sizing guidelines as regular bras, so it’s important to evaluate how your current bra fits before selecting a strapless option. If your band is riding up, you might need to go up a size or two. If you’re unsure of your size, check out our bra measuring guide or schedule a fitting at your local bra boutique. Additionally, sizing can vary between brands, so always consult the brand’s online size guide and try on the bra before committing to wearing it.

Every bust is unique, so it’s important to factor in extra features that suit your shape. For smaller chests, Caldwell suggests, 'A high center gore may press into your chest, so opting for a lower center gore could help ensure your bust fills the cup properly.' For fuller busts, Caldwell advises the opposite: 'A high center gore, paired with a wide back, is key to anchoring your strapless bra securely.'

When trying on a strapless bra, ensure the center gore sits flat against your sternum, and that your breast tissue fits within the side boning. The band should provide a snug fit, almost like a tight embrace, but still allow for a finger or two to slide behind it without being overly tight or uncomfortable. If anything doesn’t feel quite right, it may be necessary to try a different band size, cup size, or style.

Style

Just like with traditional bras, strapless bras come in various styles, so finding the right one depends on your specific needs. The most common style is the classic underwire strapless bra, which works well under any strapless or off-the-shoulder outfit. Many strapless bras today feature silicone banding, which creates added friction to help prevent slipping.

'Wire-free strapless bras are becoming very popular,' says Caldwell. 'They utilize new technology, incorporating a firm molded cup that mimics the support of an underwire and helps keep the bra securely in place.' While these bras provide excellent shaping, Caldwell acknowledges they may not suit everyone. 'For fuller-busted individuals, an underwire may be a better option due to the height and depth of their bust,' she notes. 'It can be difficult to fit a full bust into a wire-free cup while maintaining a smooth fit.' That said, wire-free bras offer added push-up, which Caldwell mentions helps keep the base of the bra snug against the body, especially for those with smaller busts.

Full coverage strapless bras are another popular option, offering a smooth look under clothing. However, to find a full-coverage bra that seamlessly fits your bust shape, you may need to try several options. Caldwell points out that if the bra doesn't match your shape, it can dig into your skin, potentially creating an unwanted outline under your clothes.

For added support and shape beneath a low neckline, consider a plunge bra, like the Natori Feathers Strapless Bra. These bras feature a low-cut front that helps support your bust without being visible. 'A well-made plunge bra will give you a flattering sweetheart shape and should still offer full coverage,' Caldwell explains. 'Even with a shorter center gore, it needs to rest gently on your body to ensure it stays in place and prevents any spillage.'

Support

When it comes to strapless bras, the band is the main source of support, which is why getting the correct size is essential. Strapless bras typically have a tighter, wider band compared to regular bras to make up for the lack of straps. The band should fit snugly without sliding up, gaping, or digging into your skin. Additionally, look for multiple rows of hook closures to adjust the fit as necessary. 'A wide band with power mesh or side support is ideal for staying up,' says Caldwell. 'Silicone grips along the top and bottom of the band provide extra security to keep it in place.'

For those with a fuller bust, Caldwell suggests looking for features like multiple hooks and clasps, side support on the back band, and grips on both the top and bottom to ensure the band stays wide and offers sufficient surface area for support. Also, pay attention to the center gore, as this is the part that helps secure the bra in place across the band in the back.

The underwire of your strapless bra plays a crucial role in providing support. Caldwell explains that the wire forms a frame on the front of the bra, which helps to maintain its shape and anchor the bra to your body. The underwire extends around the bust, from the front across the torso and in between the breasts, ensuring the bra stays secure throughout wear.

More Strapless Bras to Consider

Intimissimi Giada Microfiber Bandeau Bra: This strapless bra offers excellent support and structure, making it nearly invisible under clothes—even after frequent washes. However, we found the band to be a bit too tight, which made it feel constrictive at times.

Third Love 24/7 Classic Strapless Bra: We appreciated the full coverage and sleek appearance of this bra, but we did notice that the side boning was uncomfortable and dug in. Additionally, despite the band fitting snugly, the bra slipped down throughout the day.

Questions You Might Ask

Should you go down a size when buying a strapless bra?

It is generally recommended to size down when purchasing a strapless bra, but not for the reason of making it more secure. According to Caldwell, many people tend to wear a band size that is too large, meaning the correct size could actually be smaller than usual. "Start with the loosest hook to ensure a snug fit, and as the bra stretches over time, you can tighten it to maintain a firm hold," she advises. "Strapless bras tend to be tight initially and will stretch out."

How do you keep a strapless bra from falling down?

Preventing your strapless bra from slipping down is all about finding a proper fit. Caldwell explains, "It's not just about tightening the band. It's essential to find the right cup size that accommodates all of your breast tissue, so the underwire and band stay securely against your body." She also suggests looking for strapless bras with wide bands, a higher center gore, side support, and silicone grips for better hold.

Can people with large busts wear strapless bras?

Those with fuller busts can definitely wear strapless bras, though they may face some challenges in terms of support without straps, Caldwell explains. 'The straps play a crucial role in ensuring the cup stays snug against the body, which can be difficult for someone with a narrower torso and a fuller bust to keep the cup properly in place and prevent it from slipping out or shifting forward,' she notes. If you're uncertain about finding your right size in stores, Caldwell suggests shopping online, where a wider range of options is available. Specifically, we recommend the Curvy Kate Luxe Strapless Bra for those with larger busts.
