Removable bra pads are useful when you want a little extra coverage or shape, but they can be annoying when they fold or slide after laundry. Most of the time, the fix is simple: take the pad out, smooth it flat, and return it slowly rather than trying to straighten it through the fabric.

Take the pad out before forcing it flat
Find the small opening inside the cup and gently remove the pad. Lay it on a towel and smooth from the center outward with your palm. If it has a firm crease, dampen it lightly, reshape it, and let it air-dry flat. Do not iron it; heat can damage foam.

Put it back in with the curve facing outward
Fold the pad gently in half, guide it through the opening, then release it inside the cup. The fuller, curved side should follow the cup shape. Use your fingers from the outside of the fabric to spread the edges until the pad sits evenly. Check both sides before putting the bra on.
If the pad shifts while you wear it, the cup may be too roomy or the pad may no longer match the garment. In that case, a smooth style with built-in structure can be easier for everyday wear.

Prevent the same problem next time
Remove pads before washing whenever the garment allows it, or wash the bra in a mesh bag on a gentle cycle. Dry pads flat and return them only when both the pad and bra are fully dry. A few seconds of care at laundry time prevents the bunching that makes a top look uneven later.
Check the pad position under your usual top
Before leaving, put the garment on and view it in natural light. Run a flat hand over each cup and look for a sharp edge, fold, or uneven shape. If the pad still looks wrong after two careful attempts, remove it for the day if the garment works without it. Comfort and a smooth result matter more than forcing a worn-out insert to behave.
Know when to replace the pads
Foam that has permanently curled, thinned, or developed a hard crease may not recover. Replacement pads in a similar shape can help, but they should sit flat and not overfill the cup. If the garment has built-in structure, it may be more practical to wear it without removable pads than to keep adjusting an insert that no longer fits.
