Vertical Underwire - Heavy Gauge Wires - Replacement Wires

This is a heavy gauge 1/8 inch wide by 1/16 inch thick. Vertical wires are straight up on the ends. Regular wires have a 1/2 inch spread at the top. These wires are ideal for replacement wires in larger cup sizes from F through K.

The Vertical Underwire is generally used on larger cup sizes for an omega shaped bust. The wires are narrower than the regular underwire, but longer. Not all manufacturers use the recommended wire sizes, so check measurements carefully. If you are still unsure of which size you might need, you can order various sizes and return whichever sizes you don't end up needing.
