When it comes to lingerie, there’s one big debate that every woman faces: to wear or not to wear an underwired bra. Which is better? Which is more comfortable? And most importantly, which one should you wear? When it comes to lingerie, comfort and support are non-negotiables, but we know every woman’s needs are different. Some days call for structure and shape, others for softness and comfort. So, how do you decide which style is right for you?
What Is an Underwire Bra?
An underwire bra is designed with a thin, supportive wire sewn into the cup to lift and shape the bust. This wire helps contour your natural shape, offering lift, support and definition exactly where you need it. They’re especially great for those with fuller busts or anyone who wants a more sculpted silhouette that feels secure all day long. Our Memory Full Coverage Bra is a customer favourite for this reason
Why We Love Underwire Bras
Underwire bras are a must-have when you need a polished, lifted shape under structured or form-fitting outfits. They offer support and definition and keep everything in place throughout the day. Whether you’re heading to work, out for dinner, or wearing something sleek and tailored, the underwire provides that contoured fit that holds its shape beautifully.
When to Choose Underwire
If you have a larger bust, an underwire bra can help distribute weight more evenly and offer extra support. They’re also a great choice when you want more defined shaping or are wearing a fitted outfit that needs a smooth silhouette underneath.
What Is a Wireless Bra?
Wireless bras skip on the wire but not the support. Thanks to smart design and quality fabrics, wire-free styles offer a softer, more natural feel. This makes them perfect for lounging, travel or days when comfort is the top priority. Just because there’s no wire doesn’t mean there’s no structure. Modern wireless bras, like our Attitude Wireless Plunge Bra, are made to feel comfortable, supportive and shaped to hug your curves all day long.
Why We Love Wireless Bras
Wireless bras are the unsung heroes of your lingerie drawer. Ultra-comfortable and gentle against the skin, they’re ideal for relaxed fits and everyday casual wear. Many women also find wireless bras helpful for sensitive skin, pregnancy or travel when softness is key. They’re perfect for days when you want to feel supported without feeling restricted (and they still look just as beautiful).
When to Choose Wireless
Wireless bras are your go-to for slow Sundays, working from home or long-haul flights. If you have a smaller bust or simply prefer a more natural, laid-back shape, wireless styles will feel like a dream. They offer light support without sacrificing style. Our Supersoft Convertible Wireless Bra is a favourite for exactly that reason, offering an effortless, second-skin feel you’ll want to wear all day.
Which One Should You Wear?
Truthfully, it’s not about choosing one forever. Your bra wardrobe can (and should!) have both. Think of wired and wireless bras the way you do jeans and leggings - each has its moment. Whether you're reaching for the structured support of a wired plunge or the buttery comfort of a wireless bralette, we believe your bra should never be a compromise. There’s no right or wrong, just what feels best on the day.
Our Most Frequently Asked Questions About Underwire & Wire Free Bras
Answered by our Fine Lines Lingerie Fit Experts
Q: What are the disadvantages of underwire bras?
A: While underwire bras offer structure and support, they’re not for everyone. If the bra isn’t the right size or fit for your body, it can cause the underwire can dig, poke or become uncomfortable after a few hours of wear and some women also find them restrictive. If you’re looking for a happy medium between a bra and a bralette why not try Weightless Underwire Plunge Bra. The cups are made with a double layer of buttery-soft fabric that gives a smooth and flattering finish, offering the freedom of a bralette with the stability of an underwire bra.
Q: Which type of bra is best for daily use?
A: For everyday wear, you want a bra that combines comfort with just the right amount of support. A wireless bra is perfect for long days at home. The Supersoft Convertible Wireless Bra is incredibly soft and smooth under clothing and the under bust lattice elastic detail creates added support and fit. But, if you need a little more structure, our best-selling Refined 5 Way Convertible Bra offers dependable support and shaping (plus, it offers 5 different ways to wear).
Q: Do underwire bras help with sagging?
Yes, they can. Underwire bras are great for providing lift, shaping and support, especially if you have a fuller bust. They can help create a firmer, more defined look, which can minimise the appearance of sagging. If you’re looking for a supportive yet comfortable option, try the Memory Blessed Full Coverage Bra. Its structured cups provide the support you need, while the soft materials ensure a comfortable fit all day long.
Q: Why is my underwire bra so uncomfortable?
A: A well-fitting underwire bra should never feel painful or uncomfortable. If your underwire is causing you discomfort, it’s likely due to an improper fit. Common culprits include a band that’s too tight, cups that are too small or a wire that doesn’t sit well with your natural shape. Consider rechecking your size or trying a bra with a softer underwire.
