Finding the right strapless bra can be a total game-changer. Whether you're slipping into an off-shoulder top or dressing up for a special occasion, it's not just about ditching the straps—it’s about feeling supported, secure, and comfortable all day (and night) long. In this guide, we’ll walk you through everything you need to know about strapless bra sizing, fit and support—so you can wear your favourite strap-free styles with complete confidence. You can also explore our Strapless Bra Collection to see what might work for you.
How Do You Know What Size Strapless Bra to Get?
Without shoulder straps to help out, a strapless bra relies entirely on the band for support—so getting the fit right is essential. While the band in a regular bra does around 80% of the lifting, in a strapless style, it does 100%. That’s why it needs to sit firmly around your rib cage—secure, supportive, and comfortable without digging in.
Some women may need to tweak their usual bra size for the best strapless fit. Often, that means going down a band size and up a cup size to get that stay-put feeling that lasts all day. This can be especially helpful if you’re on the smaller-busted side and need the bra to hold its shape more firmly.
Not sure where to start? A professional virtual fitting or in-store fitting at DeBra’s can make all the difference—especially when it comes to those subtle but important size shifts.
How to Get a Strapless Bra to Fit Properly
A properly fitted strapless bra should stay in place without constant readjusting. It should lie flat across your chest, with the cups fully enclosing your bust and the band remaining horizontal and firm.
Many strapless bras include hidden design features that help them grip and stay put. Silicone slip grips, seamless cups, and reinforced side boning are just a few details that can keep everything in place comfortably. The bra should feel firm around your rib cage, yet still allow you to move and breathe with ease. For example, styles like the Elomi Smooth Strapless Bra or the 365 Smooth Moulded Strapless Bra are known for their all-day comfort and reliable hold, even for fuller busts.
If your bra slips down or gaps at the cups, it’s likely a sign the fit isn’t right — either the band is too loose or the cups too large. It’s worth trying a few sizes or styles until you find the one that fits snugly and stays secure.
How to Choose a Good Strapless Bra
The best strapless bras are built with structure, support, and comfort in mind. Look for features such as underwire, wider bands, and well-shaped cups that provide natural lift and shaping.
Fabric matters too. A great strapless bra should feel smooth under your clothes and be made from breathable, comfortable materials that move with you. If versatility is important, try the Aura Moulded Strapless Bra—a customer favourite that comes with detachable straps, so you can wear it strapless, halter, one-shoulder or crisscross depending on your outfit.

Which Strapless Bras Work Best for Different Body Types?
If you have a small chest, lightly padded styles with a contoured shape, such as the Red Carpet Strapless Bra, help to enhance your bust while keeping the bra in place. These can also prevent the cups from collapsing or wrinkling under clothing.
For fuller busts, choose strapless bras with structured underwire, wider bands, and internal support panels, such as the Dana Strapless Underwired Bra. These features work together to offer lift, shape, and confidence without the need for straps.
Regardless of your shape or cup size, the goal is always the same — to find a bra that stays in place and feels comfortable from morning to night.
Wearing Your Strapless Bra with Confidence
A great strapless bra allows you to wear strap-free fashion confidently. Always try it on with the specific tops and dresses you plan to wear, so you can see how the shape looks under clothing. This is especially important with off-the-shoulder, halter, or low-back styles.
To keep your strapless bra in top shape, it’s important to care for it gently. Avoid hot water, harsh detergents, or tossing it in a hot dryer—these can break down the elastic and damage the silicone grip. Instead, stick to cool or cold water, hand wash when you can (or use a delicate cycle in a lingerie bag), and always air dry it flat.
