Quick answer
Underwire poking usually means your bra no longer fits or the wire has worn through its casing. Start by checking the fit, then repair or replace the bra—don't keep wearing one that hurts.
Why underwire pokes: three common causes
The most common reason an underwire pokes is that the bra no longer fits. Over time, weight changes, pregnancy, or simply the natural aging of the band can alter how the bra sits. When the band is too loose, the cups shift and the wire can dig into your ribs or underarm.
Another frequent cause is wear and tear. The fabric casing that holds the wire can thin or tear, allowing the metal tip to poke through. This often happens after many washes, especially if the bra is machine-dried.
Finally, the bra may be the wrong shape for your body. If the wire is too narrow or too wide for your breast root, it will press against breast tissue or your armpit, even when the band fits well.
When to repair vs. replace
A simple repair can extend the life of a bra you love. If the wire is poking through a small hole in the casing, you can often patch it or push the wire back in and seal the opening. However, if the wire itself is bent or broken, or if the bra has lost its shape, it's time to replace it.
Wearing a bra with a broken wire is not only uncomfortable but can also damage the fabric further or irritate your skin. If you've repaired the same bra more than once, or if the band no longer sits snugly, invest in a new one.
Diagnose and fix your poking underwire
- Check the fit: Put on the bra and scoop your breast tissue forward. The wire should lie flat against your ribcage, not on breast tissue. If the band rides up in the back or the cups gap, the fit is off. If the band rides up more than an inch, the bra is too loose.
- Look for casing damage: Feel along the wire channel for any holes or thin spots. If you find a small opening, use a needle and thread to stitch it closed, or apply a small piece of moleskin over the tip inside the bra. A temporary patch can hold for a few wears, but it's not a permanent fix.
- Replace the bra if needed: If the wire is bent, broken, or the bra has lost its shape after multiple repairs, stop wearing it and buy a new underwire bra. Continuing to wear a damaged bra can cause skin irritation or further injury. Consider a new bra with a well-constructed wire casing, like the Violet Underwire Bra.
