The Best Strapless Bras For Every Bust (And Neckline)

Shopping for strapless bras is easy when you have these expert tips in hand.

Summer is here—and with it comes a slew of chic summery outfit options that may require one very specific undergarment. If your outfit involves a strapless, one-shoulder or halter neckline, a Y-back tank top or anything with a cutaway silhouette around the arms and shoulders, then you’re going to need a strapless bra to make it work.

Finding a winner doesn’t have to be Mission: Impossible, as long as you know what to look for in order to achieve a perfect fit. Seeking expert help can do wonders, too. “Most women are not wearing the correct bra size and this can greatly affect the staying power and comfort in a strapless bra,” says Marie Josée Koury, a Montreal-based fit specialist with Wacoal Canada. “If the band is too loose, it will not stay in place and will feel very uncomfortable. Buying the correct size becomes even more important in a strapless bra.” A professional fitting to verify your current size (because the girls are always evolving!) is the most effective approach to dialing down the frustration often attached with bra shopping.

With your correct sizing on hand, the search can begin. Koury recommends styles with tightly knitted fabric. “You want limited stretch, to ensure your bra will always fit you tightly over time, which is especially important in a strapless bra,” she says. She also looks for mesh-lined wings for enhanced contouring and support, plus medical-grade silicone along the inner edges for staying-put power. Another technical detail called side boning plays an important role. “It helps breast tissues stay forward, giving you a nice push, instead of spreading under your arms.”

At the trying on stage, there are several clues that a strapless won’t let you down beyond the change room. Snug is the ideal objective here: The band size should be tight but comfortable. Then, take a seat. “When we sit, our rib cage expands,” explains Koury, so it’s important to test whether you still feel comfortable. If sitting makes things too tight try adjusting the hook and eye position. Next, make sure everything is where it should be. “The underwire has to completely encircle the breast, and cups should be filled without overflowing or cutting into flesh. There also shouldn’t be any gap or space at the cup edge, and the front of the bra should rest flat against your sternum.” Lastly, check your angles to confirm a proper fit. “Ensure the back band is leveled with or lower than the front of the bra,” she says, “When you look at your side view the bra band should be parallel to the floor, not pulling up.”

For those who are in between sizes, Koury suggests choosing a style that fits a little tight and using a band extender as needed. “If that doesn’t work for you, another option is to get the band in the next size up and have an alteration made by a seamstress, like a dart on the wing. Some boutiques will offer this service,” she says. And if you have a fuller bustline, seeking out plus-size bras specially designed for ample curves can be a game-changer. “Look for strapless bras with wires that are long, at the cups they should be almost on the same level at the centre and under the arms. This will deliver more support and comfort,” she says.

What if everything on the checklist doesn’t check out? Give an alternate brand a try, because fit can vary amongst labels.
