The modern world of Lingerie is all about underwires. But do you ever wonder, what are underwires for in our bras and how and what are they made of? What are the different types and shapes of underwires, and what does each one do? What do you need to look for when purchasing an underwired bra or even when making one?
What is an Underwire?
An underwire is a thin, semi-circular strip of rigid material fitted inside the brassiere fabric. The wire may be made of metal, plastic, or resin. Plastic has the tendency to break, so is generally used in cheaply mass-produced undergarments, or in swimwear to avoid rusting. Generally, underwires are carbonized steel with an outer coating of nylon and an extra coating on the ends. It is sewn into the bra fabric, under each cup from the center gore to under the wearer’s armpit. The wire helps to lift, separate, shape, and support a woman’s breasts.
History of underwires
In 1931 a U-shaped wire was devised to be worn against a flat chest wall. It is a closely similar design to the underwires we know and have today. During the 1930s and 40s, U-shape and even O-shape wired bras were developed. Soft triangle bras, slips, and camisoles remained more popular whereas underwired bra only took off by 1950s. Many bras had over wires instead, which gave no shaping or support, just a fashionable silhouette. The modern era underwires are thinner than our breasts, once sewed into a bra, it disappears underneath. The cups and the sides of a bra form a cantilever which lifts the breast upwards from the base.
Do Underwires help Asymmetrical and Big Breasts?
Most women have one breast smaller than the other. But wires, of course, are identical providing a more symmetrical base. The main function of the underwire is to push the breast into a proper shape. Somewhat like putting play dough through a mold the breast is compressed inside the wire outline. The breast volume is pushed in a chosen direction giving a fashionable shape for the specific type of bras.
