Description
White plastic bra underwires are a viable alternative to classic metal underwires. They are ideal for those seeking lightness, flexibility and increased resistance to moisture. Available in 5 sizes, from the 1st to the 5th, they are sold in pairs (one right and one left), ready to be inserted into your sewing projects.
This type of underwire is particularly suitable for swimwear, beach or gym bras, or garments that must withstand wet conditions or frequent washing. Plastic, in fact, does not rust and retains its shape over time, even when exposed to water or sweat.
The ergonomic shape ensures proper cup support while being a more flexible material than metal. This makes it perfect for those seeking lighter and less rigid support. It’s a popular choice among sewing enthusiasts, artisans, and seamstresses who want to experiment with alternative, functional materials.
The white color is easily adapted to light-colored fabrics or work where the underwire may be slightly visible. It is ideal for those who sew custom lingerie, sports underwear, or handmade swimsuits.
The underwires are usually placed at the base of the cup by using an underwire casing that is attached near the bottom seam.
