Long length metal underwires


Premium quality metal coated with a non-stick finish. If you are making a the Classic Bra these wires will be the ones you need. 

The industry standard wire with coverage a bit higher than the apex line in most sizes. Long wires are the length of wire most often needed for replacement in bras found in ready-to wear. You can then compare our wires to the ones that are closest to yours.

Bra-Makers Supply have published a great document of Must-Know Information for underwires to help you calculate the correct wire size. Click here to open the pdf in a new page.

If you have a wire from an old bra that fits you well, there is also a chart that you can print off at 100% to check the equvalent wire size.  Click here to open the pdf in a new page.
