Wireless vs. Underwire Bras: See Which Style Is Best for You

To wear wire or not to wear wire…the decision is really up to you. Though wireless bras and underwire bras each have their own benefits, one style isn’t necessarily better than the other. It’s all about personal preference. In case the difference between the two isn’t clear, one is designed with wire that supports the shape of the cup while the other is free of wires completely. Read on to find out which style is best for you.

Underwire Bras: Pros and Cons

There are common misconceptions about wired bras when it comes to the topic of breast health and comfort. For one, underwire bras can be comfortable as long as you’re wearing the correct size and the bra is made of quality materials (like our flexible, no-poke underwire). As for the link between breast cancer and bra wear, there’s no scientific evidence to support the myth that wearing a bra poses a higher risk for cancer. However, sleeping in a bra that’s too tight may cause issues such as restricted blood flow, skin irritation, and worsened symptoms of acid reflux. Now, let’s get into the perks and pains of underwire bras.

PROS: Underwire bras do provide more support and shape, thanks to their wired structure. We recommend this style for women with larger breasts who may want more support in their everyday bra. If lift is what you’re looking for, underwire bras offer your breasts more lift than a wireless bra does.

CONS: Some women just prefer to go wire-free altogether. Even if the bra is a perfect fit, you may still find a wireless bra to be more comfortable.

For a supportive underwire bra, try our 24/7™ Classic T-Shirt Bra. ThirdLove customers often forget they’re even wearing our signature bra.

Although it’s always a great time to go wireless, we say it’s especially perfect for lounging, napping, and running errands. But you can also replace your everyday bra with a wireless one, depending on the amount of support you need.

PROS: Wireless bras can offer the same great benefits of a wired bra without wires. As long as it features a comfortable band and supple, stretchy fabric, you should be able to enjoy light support and maximum comfort.

CONS: Without wires, you’re left with less structure. A wireless bra won’t give you the same silhouette as you would get with a wired bra, which will be noticeable when wearing fitted tops. And if you have larger breasts, a wireless bra probably isn’t enough to offer you the everyday support you’re looking for.
