Bra underwires are always a huge concern, and it's even more bothersome when the wire just doesn't fit correctly. Rather than struggling with a poor fit, it is often a better idea to subtly bend the underwires for a more personalised feel. To make your underwire fit comfortably, bend the wire delicately and adjust the wire shape to your body’s curve, particularly at the armpit and sternum. It sets out more room for the skin or improves the way the bra supports the breasts. This is achieved by lightly flexing the metal away, followed by gentle and repeated bends until the fit is right, while being careful to avoid over-bending or distorting the wire.
Why Underwires Don't Always Match Your Shape
Most underwires are manufactured as perfectly flat 2D objects. However, the human ribcage is a 3D cylinder. This fundamental mismatch in shape often leads to several fit issues:
- Pressure Points: The wire may dig into the underarms or the center of the chest.
- Poor Positioning: The wire may rest on sensitive breast tissue rather than encircling it.
- Empty Space: You might notice a gap at the bottom of the cup because the wire cannot sit flush against your skin.
- General Discomfort: Even if the cup and band size are technically correct, the "flatness" of the wire can make the bra feel restrictive or painful.
How Your Underwire Should Sit
To ensure your underwired bra is doing its job comfortably, check whether the underwire following these three rules:
- Contour: It should sit flat against your ribcage, mimicking the natural curve of your body.
- Enclosure:The wire should fully encircle the breast, sitting flat against your ribs just behind the breast tissue toward your armpit.
- Stability: The breast should remain fully supported within the base of the cup, preventing the underwire from lifting away from the chest wall.
Because everyone's ribcage is shaped differently, a slight manual adjustment to the wire can often bridge the gap between a "standard" fit and a "perfect" fit. By gently curving the wire to match your body's arc, you ensure the bra works with your anatomy rather than against it.
When Should You Consider Bending Your Underwire?
You might consider gently bending your underwire if you notice any of the following:
- Your bra feels uncomfortable even though it’s the right size
- The bottom of the cups doesn’t sit smoothly or feels slightly empty
- The underwire presses or pokes into your underarm area
- Your breasts don’t settle naturally into the cups
These are typically fit-related concerns rather than signs of poor quality—and they’re often simple to correct.
How Underwires Are Adjusted
Underwire adjustment is an important step to transform a bad fitting bra into a good source of support and all-day comfort. You can avoid painful poking and ensure the wire contours perfectly to your breasts by mastering a few simple techniques.
1. Understand the Concern

- Poking or Digging in Armpit: Identify whether the wire is digging into your armpit, sitting too low or high on your breast tissue, or failing to sit flat against your sternum.
- Unfilled Cup Base: You need to widen the underwire in a bra slightly if the sweep is too narrow for your frame.
- Body Lift: The wire is not supporting your chest wall curve.

2.Reshape Your Underwires

- If digging in the underarm, widen the sweep: Make the wire shallower to give the breasts more room. Hold the wire in the centre and gently bend it outwards, away from the centre.
- Narrow the sweep for gaps: Make the breasts fall into the cup by holding the wire and gently bending the ends slightly inward to create a narrower U-shape.
- Align with your rib cage: Gently bend the wire to match your specific ribcage curve if the wire tilts back. Ensure it sits flat against your sternum and under your breast root.
- This adjustment can: Allow your breasts to settle more naturally into the bottom of the cups, reduce or eliminate gaping at the base, and enhance overall comfort and support.

- Use your thumbs to gently flex the wire into the desired curve.
- Try on the bra immediately after each small adjustment. It is easy to overbend, so it is better to make minor changes and repeat the process as needed until you achieve the perfect fit.
Follow the Important Safety Tips

- Be Gentle: Small bends are better than big ones because wires can be distorted easily.
- Check the Fit: The underwire in a bra should not sit on top of the breast tissue; it should rather sit under it so that it doesn't poke your armpit. If the wire constantly pinches the sides of your breasts, the sweep may be too narrow. In these cases, bending might not provide a solution, and a larger cup size or a different wire style may be necessary.
- Be Mindful to Size Up: If bending the wire does not fully contain your breast tissue, you likely require a larger cup size.
- Make Small Extensions: Bend the wire very lightly and try the bra on frequently. It is much easier to add a slight curve than it is to rectify a wire that has been over-bent or badly distorted.
- Refrain from Bending Wire Too Often: If it is bent back and forth too many times, metal can become brittle and break.
- Avoid Excessive Bending: If a wire has already poked through the fabric, you can push it back into the casing and reinforce the hole with a moleskin patch or a small, sturdy stitch.

When Bending Isn’t Enough: Recheck Your Cup Size
If you’ve adjusted the underwire and your breast tissue still spills out or isn’t fully supported, it may be time to size up in the cup. Adjusting the wire can’t make up for a cup that’s too small.
Signs you may need a larger cup include:
- Breast tissue spilling over or sitting beneath the wire
- Ongoing discomfort even after making adjustments
- Underwires that shift or move out of place during wear
Common Mistakes to Avoid When Adjusting Underwires
- Bending the wire too much at once
- Applying force too quickly or aggressively
- Trying to adjust the wire while wearing the bra
- Making uneven changes to each side
Always take the bra off before adjusting and work gradually, checking that both sides remain symmetrical after each small change.
Caring for Underwires After Adjustment
Underwires are typically made from tempered steel, which makes them durable but sensitive to heat. To prevent damage, avoid exposing underwire bras to:
- Tumble dryers
- Direct heat sources
- Harsh or high-agitation wash cycles
Heat can weaken the wire, making it brittle and more prone to snapping. Hand washing or using a gentle cycle followed by air drying helps preserve both the shape and longevity of your bra.
Why Underwires Lose Their Shape Over Time
Underwires can gradually change shape due to:
- Regular washing
- Packing and storage
- Folding during travel
- Everyday wear
This is completely normal. Gently reshaping your underwires is a safe and effective way to customise the fit and restore comfort.
Final Note
Fixing your wired bra is a simple DIY task that can remarkably enhance comfort and prolong the life of your bras. By making small, incremental bends to the metal, you can eliminate painful pressure points and ensure the bra follows the unique contours of your ribcage.
However, if you find yourself constantly bending wires or if they frequently pop out of the fabric, it may be a sign that the bra size or shape is incorrect for your body. Always give preference to a professional fitting if manual adjustments do not render a sustainable solution.
FAQs
- Can you bend underwire bras for a better fit?
Yes, gently bending an underwire can improve both comfort and fit. Small adjustments allow the wire to better match your natural body shape, easing pressure under the arms and improving support.
- Is it safe to bend bra underwires?
Yes, when done slowly and carefully. Underwires are made from tempered steel and are designed to tolerate minor shaping, but they should never be bent forcefully.
- Why does my underwire dig into my underarm?
This usually happens when the wire is too straight for your body or rests on breast tissue. Slightly reshaping the center or narrowing the curve can help reposition the wire more comfortably.
- How can I tell if my underwire fits properly?
A well-fitting underwire lies flat against your ribcage, fully encloses the breast tissue, and sits comfortably behind the underarm without poking or pressing.
- Can bending underwires help with gaping at the bottom of the cup?
Yes. Gently curving the ends of the wire inward can help your breasts settle into the base of the cups, reducing gaps and improving support.
- When should I size up instead of adjusting the underwire?
If breast tissue still spills out or isn’t fully supported after adjusting the wire, it’s likely time to move up a cup size. Wire adjustments can’t fix cups that are too small.
- Will bending underwires damage my bra?
Careful, minimal adjustments won’t harm your bra. However, frequent forceful bending or exposure to heat can weaken the wire and lead to breakage over time.
- Can underwires lose their shape after washing?
Yes. Washing, drying, packing, or storage can cause wires to shift or warp. This is normal and can usually be corrected with gentle reshaping by hand.
- Should underwire bras go in the dryer?
No. Dryers expose bras to high heat, which can make the wire brittle and shorten the life of the bra.
- How often can I adjust my underwire?
You can reshape your underwire whenever it feels uncomfortable or out of shape. Occasional adjustments are normal and help maintain a comfortable, personalised fit.
