Regular Underwire - Replacement Wires

Note that this particular style is discontinued. The heavy gauge is our new style. Note that not all sizes are available in this style. The sizes in the drop down are the only sizes available. These are nylon coated underwires. The colored ends indicate the center front of the bra.

These are traditional regular underwires that fit the average of bras. Not all manufacturers use recommended sizes and styles, so please check the measurements against any wires you are replacing. If you are making a custom bra for the first time, I recommend purchasing 3 wires - one that is recommended and once size up and down from the recommended sizes. You can return any unused wires.
