The Best Non-Wired and Wireless Bras

Jayne Cherrington-CookAre non-wired bras better?
If you’ve ever walked through your front door and unhooked your bra faster than you’ve hung up your coat, you already know why non-wired styles are having a moment.
More of us are choosing comfort over traditional wired styles for everyday wear as they still offer the support you need, but with a more flexible feel and no wires digging in.
So, are non-wired bras better? For comfort-led days, absolutely. And whether you prefer a sporty crop top, a seamless second-skin fit or a classic wire-free shape, the best wireless bras now provide reliable support, optional padding and a natural silhouette that moves with you, making them a must-have for most lingerie drawers.
What to look for in a supportive non-wired bra
There’s a myth that wireless bras can’t offer proper support but today’s designs prove otherwise. The best supportive non-wired bras rely on smart construction rather than rigid wiring, giving you lift, shape and comfort in equal measure.
Look for details that do the heavy lifting. The best supportive wireless bra will have a wide, stabilising underband, moulded or lightly padded cups – with fuller cups offering more coverage and control – plus clever seam placement that supports the bust without adding bulk.
At M&S, our non-wired full cup bras and total support styles are designed with all-day comfort in mind and our non-wired fuller bust bras go up to a 46K, showing just how supportive wire-free can be.
How should a non-wired bra fit?
If you’re unsure how your wireless bra should fit, it follows the same principles as with any wired bra. Getting the right size is the key to finding the best non-wired bras for everyday comfort.
Start with the underband. It should feel comfortably firm, not tight, and you should be able to slide two fingers underneath without effort.
Cups are key too. They should sit flush against your skin – no gaping, no bunching – and seams should feel smooth and supportive. Then check your straps. They should lift gently without digging in or slipping off.
If you’re not confident with your current size, you can find step-by-step guidance on how to measure your bra size at home or book an expert in-store fitting through our bra fit service.
Wired vs. non-wired: which is better for you?
If you’re weighing up wired versus non-wired bras, think about how you’re planning to wear them. Wired bras – like our everyday wired styles, smoothing T-shirt bras and flattering plunge designs – give great lift and shape, making them ideal for more structured outfits.
Non-wired bras are all about comfort. They’re softer, more flexible and made for days when comfort is the plan, whether that’s everyday wear, working from the sofa or heading to yoga in our non-wired sports bras.
When you’re deciding whether a wired or non-wired bra is better, there’s no right answer. Choose the structure of wiring for those “pulled-together” days and the ease of wire-free when comfort is a top priority.
