Best Bras for Backless & Low Back Dresses

A backless or low back dress is one of the trickiest outfits to wear a bra under — but it's far from impossible. Below, our expert fitters share their tried and tested solutions for open back styles, from convertible bras and bodysuits to adhesive options and accessories for when a traditional bra simply won't work.

Why These Items

This collection has been put together deliberately to cover the spectrum of backless outfit challenges. The two convertible bras here - the Refined 5 Way Convertible and the Refined 5 Way Liquid Convertible - have been around for a long time and are genuinely reliable; we've recommended them to thousands of customers and the feedback is consistently good. Their multiple configuration options mean they adapt to different dress styles and back heights, making them some of the most versatile bras in our range. Because the band sits lower to stay hidden, the straps take on more of the support role than in a standard bra - which is why fit through the strap length and shoulder placement matters more than usual with these styles. The two bodysuits offer a plunge front with a low or open back, giving you structure and coverage where you need it most. The accessories - boob tape and stick-on bras - round out the collection for outfits where even a low band isn't an option.

How to Find the Right Support for a Backless Outfit

The challenge with backless and low back dresses is that the band - which normally does the majority of the support work - either needs to sit much lower than usual or disappear entirely. That changes how support is delivered, and it's worth understanding your options before you reach for the first adhesive bra you find. For dresses with a low back rather than a fully open one, a low back bra is often the simplest solution. For more open styles, a convertible bra worn in a configuration that keeps the back clear is a reliable choice that still gives you underwire support through the straps. When the back is too open for any band at all, adhesive options - stick-on bras and boob tape - step in as your support as a standalone solution specifically for busts on the smaller side. Bodysuits with a plunge or low back are an underrated option that many women overlook - they provide full coverage at the front, disappear at the back and give you the added benefit of staying tucked in all night.

Can I wear a regular bra under a low back dress?

Yes - the key is choosing a style where the back sits low enough to stay hidden. A convertible bra worn in a halter or crossback configuration removes the traditional back band from the equation while keeping the underwire support intact through the straps. For dresses where the back is open entirely, adhesive bras or boob tape are your most reliable alternatives. The right solution depends on how low the back falls and how much support you need - our team can help you work this out in store.

Are bodysuits a good option under a backless dress?

Often overlooked but genuinely excellent - particularly for women who want structure and coverage at the front without any visible bra. The plunge bodysuits in this collection sit very low at the front and open at the back, giving you a clean silhouette while staying completely secure all night. They work best under dresses with at least some back coverage, as the bodysuit itself needs somewhere to sit - but for the right dress style they're one of the most comfortable and reliable solutions we offer.

Can I get help finding the right solution for my specific dress in Melbourne?

For backless outfits especially, we'd genuinely encourage you to come in rather than guessing online. The right solution depends on where your dress sits at the back, how much support you need and how long you'll be wearing it - and those are things that are very hard to assess without seeing both you and the dress. At Illusions Lingerie in Melbourne our expert fitters deal with this question regularly and can talk you through the exact combination of products that will work for your specific outfit. Fittings for shapewear in Melbourne are completely free and no booking is required - bring your dress if you can.
