An underwire that pokes out is one of the most annoying bra problems—and one of the most preventable.
Here’s why it happens, how to fix it, and how to make sure it never happens again.
Why Underwire Pokes Out
The #1 cause: The cup is too small.
When the cup is too small, it puts pressure on the underwire, forcing it to bend and eventually poke through the fabric.
Other causes: Improper washing (especially the dryer), worn-out fabric, the wire is too narrow for your breast shape, the bra is old and the fabric has weakened.
How to Fix an Underwire That’s Poking Out
For a quick fix:
- Apply a small piece of moleskin or fabric patch over the poking wire
- This creates a barrier between the wire and your skin
- It’s a temporary solution—not a permanent fix
For a more permanent fix:
- Carefully cut a small slit in the fabric at the end of the wire channel
- Remove the wire entirely
- Sew the slit closed
- You now have a wireless bra!
How to Prevent Underwire Poking Out
| Do | Don’t |
|---|---|
| Hand-wash underwire bras | Put underwire bras in the dryer |
| Use a lingerie bag in the washing machine | Twist or wring underwire bras |
| Air dry underwire bras | Use fabric softener (weakens fabric) |
| Use the gentle cycle | Overload the washing machine |
| Fasten hooks before washing | Wash with heavy items (like jeans) |
When to Replace a Bra
| Sign | Action |
|---|---|
| Underwire poking out | Replace or remove the wire |
| Fabric is worn or thinning | Replace the bra |
| Elastic is stretched | Replace the bra |
| Underwire is bent | Replace the bra |
| Bra is 6–12 months old | Consider replacing |
Pro Tips
- Never put underwire bras in the dryer—heat damages the elastic and weakens the fabric
- Use a lingerie bag to protect bras in the washing machine
- Hand-washing is the best way to extend the life of underwire bras
- Replace bras every 6–12 months with daily wear
Conclusion
Underwire poking out is preventable with proper care and the right fit. If it happens, you have options—from quick fixes to permanent solutions.
