Regular Underwire - Heavy Gauge Wires - Replacement Wires

This is a heavy gauge 1/8 inch wide by 1/16 inch thick. These are nylon coated underwires. The colored ends indicate the center front of the bra. These wires are ideal for replacement of broken underwires on bras cup sizes A through F.

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.

We created a video on how to determine your replacement wire size: Replacing an Underwire: How to Choose the Correct Wire for Replacing a Broken Wire
