“Truth: I only wear strapless when I’m at wedding-level events," says WH managing editor Laura McLaughlin. "And if there’s one place where you can’t have a wardrobe malfunction, its at a wedding-level event." Lucky for her, Wacoal's Red Carpet Strapless Bra is universally known and respected for its reliable comfort and support. "Trust me when I say that getting through my cousin's reception rendition of The Time Warp with confidence is really important. And I did it with ease in the Red Carpet."

Fuller cups mean serious coverage, while an underwire makes sure your boobs stay right where you want 'em. This bra has both of those features, along with the welcome addition of sides that shape and smooth your figure so you can feel your most confident ever.

Our tester says this is the best strapless bra that she has ever owned says. According to her, there's no slipping and it gives great support for larger-chested girls. She has owned more expensive brands, but she claims that this one is better than all of those.

As an added bonus, this bra comes with removable straps that convert five different ways: one shoulder, strapless, criss-cross, halter, and traditional.

Testers love the look, feel, and comfort this strapless lace bra offers. With this strapless bra, you can trust that everything will stay in place with added underwire, side bonding for extra support, and silicone grips along the top edges.

One tester especially loves that it gives her the look of not wearing a bra at all. What to thank for its barely-there look? A soft mesh lining that holds the girls in place but doesn't make 'em look any bigger than they need to.

Strapless bras are often saved for special occasions, but who said they had to be used exclusively for that purpose? No one. Whether you're lounging at home or running errands, this wire-free, comfortable bra allows you to feel ~free~ without going braless.

Our tester was worried about the fit, since it looked really small. However, she tells us it fit perfectly! Not only is it comfortable, but the design smooths everything out, she notes, adding that this bra stays up really well, so she's not fidgeting with it all night long.

Finally, a strapless bra that is here to take the plunge with you—literally. Now, there's no need to skip wearing that dress with the really low neckline. This bra is wire-free, comes with removable and adjustable straps, and is made with a super soft fabric you won't mind wearing all day.

One tester who despises bra shopping (especially when she does it online!) was super pleased with this bra. She notes that it fit as expected and felt secure for a strapless bra.

From renowned designer Josie Natori, the cups of this strapless bra are foam-lined for smoothness. Meanwhile, the three-column hook-and-eye closure in the back makes sure this thing stays snug. Also, the cotton-blend fabric makes for all kinds of comfy.

I'm also someone who despises the constricting feel of strapless bras, but Natori makes my all-time favorite options. They're super comfortable and very supportive, so I'm never worried about the girls popping out or drooping when I wear them. I love that this style in particular has a thicker band, so I always feel secure without feeling like I can't breath. Plus, the cleavage I get with this style is a welcome bonus.

Just because you have a fuller bust doesn't mean you have to go through the torture of underwire bras. One of our testers says she has never had a strapless bra fit so well before. She's always dealt with strapless bras that gape or slide or have too much space. However, these fit "just right" and she has not had a problem with them sliding. With soft and flexible support, plus a no-slip strip lining on the top, you can guarantee the girls won't be moving around no matter what you're doing.

WH executive fashion director Kristen Saladino raves about Cosabella's Evolution Strapless Bra (I'm a huge fan of the brand as well!). "Thanks to the super smooth microfiber fabric, the band is soft and doesn’t dig into your back, but at the same time is tight enough to stay up without adjusting all night long," she says. Plus, it gives you a bit of oomph, so the girls look good when you're wearing a low-cut dress.

Spanx started as a flattering pair of pantyhose, so it only makes sense that their foray into bras would utilize the same stretchy, smooth, shaping technology. This bra has flexible side panels and grippy strips around the cups so the whole bra moves with you, never against you.

One tester tells us that she's so glad she finally found a strapless bra that actually works. Specifically, she likes the 'smart grip' and how it sticks to the body to hold the girls up. She adds that this is really difficult to find with breasts her size.

Want to feel lifted sans underwire? This seamless bra with plunging cups will keep everything in place without sacrificing comfort. Plus, it comes in 21 colors, so you can choose whichever one (or two) fits your style needs.

This bra is also a winner for those with big breasts, per our tester. "I was nervous because I'm a 42F," she writes. But, the brilliant part of this bra is that it doesn't actually have an underwire. The support pieces are made from flexible molded plastic, so they don't stab into you the way underwire might.

Zero underwire, zero straps, zero bulging—those are our favorite characteristics of this seamless bra. It can be worn with dresses or low-plunge shirts to heighten up the girls (sans signs of sagging!) without getting in the way of your look.

One tester loves this bra so much, she has purchased five of them over the last 10 years. It's now her favorite strapless bra. With diligent care, she has gotten anywhere from 20 to 30 wearings from each.
