Collection: UNDERWIRES

Formline underwires are manufactured from high-tensile sprung steel. They offer unmatched strength and durability. Our wires are thoroughly coated and feature tipped ends to protect channels and garments. Colour coding helps identify sizes in the workroom.

To ensure correct style and fit, we recommend using our free Underwire Sizing Templates in your pattern making. Add to cart and purchase to receive a download link. There is no charge for our templates.

For absolute accuracy, we recommend purchasing wires to test or sample your garments.
