Best Wire Free Bra
Wire free bras have become increasingly popular. And it’s no wonder why! After all, they offer supreme comfort, are easier to care for and give you great support.
This latter point might seem contentious to some… It is a common misconception that in order to have the support you need (particularly for larger busts), you need an underwire. But between fabric and design innovations, this is not really the case.
After all, many sports bras are wireless bras (they’re easier to move in that way) and the last thing they compromise on is support.
So, now you’re sold on wire free bras, let’s look more closely at the features you should pay attention to when shopping...
5 Things to Look for in the Best Wireless Bras
1. Size Range / Cup Size
Whether you’re buying a wire free or an underwire bra, the right cup size is essential. This is key not only to achieving the shape you desire, but also for comfort and support. If you have a larger cup size, don’t be tempted to squeeze yourself into a smaller band or cup size. Instead, look for brands that have a wide and inclusive range of cup sizes to choose from. Knix cup sizes go all the way to 42G.
2. Lift, Shape & Support
Don’t confuse all wireless bras with a flimsy bralette. You can and should expect lift, support and gentle shaping from your wire free bra. This will usually come from the construction: Molded cups, wide shoulder and back straps will make up for the support you’d usually get from an underwire. The only difference is you won’t have a piece of wire digging into your ribs.
3. Style Options
There’s never one bra to suit absolutely every kind of body and taste. You should have choices! From colours (including the right shade of ‘nude’), to the actual style of bra - make sure you’re able to get what you want.
4. Functional Options
Very few of us confine our entire existence to one bra style. We might want something a little fancier for evenings, a sports bra for activities, a perfect, seamless T-shirt bra for everyday wear. Be clear about what kind of bra you need and make sure you fulfill that functional need.
5. Comfort
One of the biggest reasons women prefer wireless bras is comfort. For many, underwires can irritate the skin, or dig uncomfortably into the ribs. And because underwires are inflexible, they cannot expand or contract as your body changes - whether that’s because you just enjoyed a tasty meal, or you’re at ‘that stage’ of your menstrual cycle.
So if you’re swapping for a wireless bra, make sure it does offer the comfort you crave. Comfort and fit go hand-in-hand. So make sure:
- Shoulder straps stay put and don’t dig in
- Back straps can be adjusted up and down and are snug but not tight
- Your breasts stay put (seriously, do some jumping jacks) and there’s no spillage or bulging
- It's comfortable enough to wear all day

No Matter the Style, Finding the Right Size is Key
Many times when a bra is uncomfortable or doesn’t offer enough support, it’s not just the bra’s fault… it’s that we’re wearing the wrong size.
We totally get it; it’s convenient and quick to shop online. But even if you’re absolutely certain of your correct size, cup sizes can vary from brand to brand. What’s more, your body changes over time, so it’s sensible to get measured from time-to-time.
Finding the right style is as important as the right size. Do you need full coverage, lightly lined, convertible straps, wide straps, soft cup or padded cup? The choices can be overwhelming...

How to Care for Your Wire Free Bra
Once you’ve found the best wireless bra for your style and needs, it makes sense to prolong its lifespan as long as possible. The good news is that wireless bras are a lot more low maintenance than underwire ones.
Obviously, the more bras you have in your rotation, the longer they’ll last. But also key is how you wash your wirefree bra.Here are the steps to follow if you’re opting for the washing machine:
- Step 1: Fasten all the hooks / clasps. Hooks and clasps can catch on other items of clothing, which can cause a lot of stretching, pulling and even breakage of your bras. So make sure you fasten all the clasps to minimize the chances of that happening.
- Step 2: Place the bras in a mesh bag / lingerie bag. A mesh bag or lingerie bag is great for keeping delicates (underwear, socks, tights) contained in the laundry and protected from tangling with less delicate garments.
- Step 3: Separate your colors / weights. As always with laundry, you want to take a moment to separate your colors (white, black and colors). You can also separate your loads by weight, including bras with other lighter items, like tees, socks, underwear etc. rather than heavier objects like bed linens, jeans and sweatshirts.
- Step 4: Choose a gentle cycle. Make sure to set your machine on a gentle cycle or cold water cycle when you’re washing undergarments or other delicates.
Whether you hand wash or machine wash your bras, it’s your choice. But if there’s one hard rule it’s on drying: Drying machines are an absolute no-no. Instead opt for an air dry.
Why? Because the heat of dryers can be detrimental to the elastic in your bra. And once the elastic is gone, your bra is finished.
With a little care, your new favorite bra should last you a long time!
