What do wired bras do?

By definition, a wired bra has thin, semi-circle plastic or metal underwires sewn into each cup. The purpose of an underwire is to comfortably lift and contour breast tissue to create a natural shape. Underwired bras are a popular bra style amongst women of all bust sizes because they provide comfortable, everyday support. Some women prefer wired bras over wireless bras because they may provide more support.

When should you wear an underwire bra?

You can wear an underwired bra everyday. There are many different styles of wired bras to choose from that are appropriate for all occasions. There are front-closure, back-closure, T-back, and even sports bra styles of underwired bras. It simply comes down to personal preference on when you choose to wear either wired or wireless bras.

Are wired bras harmful?

No, wired bras are not harmful to your body or health. An underwired bra might only cause you pain if your bra doesn’t fit properly. When it comes to purchasing underwired bras, it’s important to measure your bra size correctly to ensure you have the right fit. Wearing the wrong bra size can cause the wires to poke you, which is never comfortable. 

What causes an underwire to break?

Wearing the wrong cup size can cause the underwires in your wired bra to break. Wearing an underwired bra in a cup size that’s too small can make the wire too tight, while too big can cause the wire to move around. Both lead to uncomfortable poking or prodding, or even cause the wire to break, none of which are comfortable.

Why does my underwire bra hurt?

Your underwired bra might hurt you if you’re wearing the wrong bra size. If the wire pokes your underarms or breast tissue, this is likely a sign that you’re wearing the wrong cup size, which can cause some pain if the wire pokes or pinches your chest or underarms.

Where should your underwire sit?

The underwires in your bra should comfortably support each individual breast. The wires should lay flat and meet in the center of your chest and reach up to your underarms, but not pinch them. The underwires should also not ride up under your breasts but lie flat against your chest in line with the rest of your bra band.

Who needs an underwire bra?

Any woman who wants a bra that provides ample support and lift might be interested in wearing wired bras. That being said, a non wired bra can provide enough support for anyone who prefers wireless bras. It simply comes down to personal preference and what fits you best.

Can you wear a wired bra when you’re pregnant?

There’s no reason why you can’t continue wearing a wired bra while pregnant. As long as your bra size is correct, the bra isn’t too tight, or you don’t feel uncomfortable, you can continue wearing a wired bra as long as it suits you. Though as your body changes, you might prefer the comfort of a non wired bra as opposed to a bra with a rigid underwire. Comfort always comes first!

Can underwires cause back pain?

Wearing an ill-fitting bra can cause some discomfort and pain, but underwires themselves aren’t to blame for causing back pain. If you’re wearing a wired bra or even a non wired bra that’s the wrong size, this can cause some discomfort and even back pain. As any woman who wears a large bra size knows, having a bra that fits well and provides the support you need is crucial for avoiding the back and shoulder strain that can come with having large breasts.

Can wired bras be washed in the machine?

No, it’s always best to wash wired bras by hand. Washing your underwired bras by hand retains the elasticity of the fabrics and the shape and structure of the underwires themselves. Machine washing your bras can damage your bras. You should also always lie your underwired bras flat to dry or hang them. The heat of the dryer can cause the fabrics on your bra to wear out faster and can compromise the shape of the wires, too.

Concluding Thoughts

When it comes to shopping for underwired bras, there are a few things to take into account, but it’s not much different than shopping for non wired bras. One of the most important factors to consider is knowing your correct bra size. Having an underwired bra that fits properly is crucial to having the support and comfort you need while also avoiding any other painful issues that can come with having the wrong fit.
