Broken underwire in your bra: what can you do?

If an underwire is broken, or already poking through the fabric, take that bra off right now. You can cover the sharp tip with a bit of tape so it doesn't scratch you, but don't wear the bra again after that. The real fix is figuring out why the wire broke in the first place, or switching to a wire-free bra.

What to do right now

Feel a sharp point poking through the fabric, or has the wire snapped clean through? Take the bra off, even if you're in the middle of your day. A broken wire doesn't get better if you keep wearing it: the tip works its way further out, and every move you make pushes the metal a little further through the fabric.

• Take the bra off the moment you feel the wire poke or scrape
• Tape over the tip temporarily if you really need to keep it on a bit longer
• Then toss the bra: once a wire breaks, it won't bend back straight

That's the quick fix. Below is why wires break in the first place, so your next bra doesn't meet the same end.

Why do wires break so often?

You're definitely not the only one dealing with this. Of the nearly 2,900 women we asked about their biggest bra frustration, 32.8% named the underwire itself: it breaks, digs in, or cuts. That's by far the most common complaint, bigger than straps, closures, and fit combined. So the wire isn't some small, occasional annoyance. It's the single biggest recurring complaint about bras, period. Below are the four most common causes, each with a test you can do right now.

1. You're washing the bra in the machine or dryer

An underwire is really nothing more than a thin strip of metal, bent into shape and sewn into fabric. In the washer, that wire knocks and twists against zippers, hooks, and other clothes hundreds of times. In the dryer, heat makes it worse. After a few washes, the metal breaks at exactly that one weak spot.

Try this: check the care label in your bra. Does it say hand wash or delicate cycle, and you toss it in with everything else anyway? Then that's almost certainly why you keep having to replace underwire bras.

• Wash in cold water, on the delicate cycle
• Use a laundry bag so the wire doesn't rub against other clothes
• Lay the bra flat to dry, never in the dryer

A bra laundry bag costs you almost no extra effort and stretches the life of every underwire bra you still have in your closet.

2. Your cup is actually too small

If your breast doesn't fully fit in the cup, the tissue pushes the wire outward, past the shape it was originally bent for. That extra push, day after day, wears out the metal fast. This is often also exactly why the wire starts poking you under the arm or at the side.

Try this: stand in front of the mirror and put a finger on the side of the wire. Does it sit away from your ribs instead of lying flat against them, or do you see tissue spilling out above the cup? Then your cup is too small. If you're currently wearing, say, a 36C and you see that happening, try a 36D or a 38C instead.

"Just had another wire poke through the fabric, and this morning a bra already went in the trash because it was digging into my armpit."

3. The wire isn't sitting in the right spot

An underwire should lie flat against your breastbone and ribs, not on the breast tissue itself. If it sits too high, too low, or crooked, it bends a little further than it's meant to with every move you make. That repeated bending is exactly where metal fatigue comes from, separate from whatever's going on with your cup size.

Try this: put your bra on properly, bend forward so your breasts actually settle into the cups, then check the center point with your finger. Does it lie flat against your breastbone? Good. Do you feel space there instead, or is the wire sitting on your breast rather than underneath it? Then the band is probably too loose, or you're not pulling the bra on tight enough before wearing it the rest of the day. A band that fits fine in the morning can still ride up later if it's too loose to start with.

4. The wire is simply worn out

Even with perfect washing habits and the right size, a wire has a shelf life. After hundreds of wears, bends, and movements, even the best metal wears out eventually. If you've worn a bra almost daily for over a year, a broken wire is really just the end of its life, not something you did wrong.

Try this: roughly count how many times a week you wear the bra and how long you've had it. Once you pass around 150 to 200 wears, nearly any wire has reached the end of its life, no matter how carefully you wash it.

Is the wire already poking through the fabric?

That's a slightly different situation than a wire that's broken inside but hasn't pierced the fabric yet. In that case, read what to do when an underwire pokes through the fabric of your bra first, so your skin doesn't take the damage before you get a new bra.

What if it keeps happening?

Is this not a one-time thing, but bra after bra? Then the problem isn't that one wire that happened to break. It's the whole idea of a wire: a thin piece of metal that bends, gets washed, and bends again, every single day, until it can't anymore. No matter how carefully you wash it or how well the size fits, at some point the material simply gives out.

A wire-free bra can't break this way, because there's no metal inside to wear out. The Daily Essential Bra gets its support from memory foam cups that mold to your shape, a 3-inch wide band that supports from below, and a double layer of shaping fabric on the sides that holds everything together. No wire to poke, cut, or snap. Just support that stays put.

If the size doesn't feel quite right at first, our 30-day perfect fit guarantee has you covered. No need to gamble blind after all the wires you've already had to toss.

Wondering if a wire-free bra can really give you enough support after years of wearing underwire? That's a fair question. Read what to expect the first time you wear wire-free before you make the switch.
