Underwire bras are built with a semi-circular "underwire", "bra wire", or "wire" embedded in the wire channel that circles the bottom and sides of each cup. One end, or head element, of the underwire is close to the front and center of the bra, and the other close to the armhole.

The underwire can be made of metal or molded plastic; most are metallic. Plastic underwires have a "tiny" share of the market because they do not provide the same support and rigidity offered by metal underwires.

Due to the presence of the underwire and its tendency to tear through cloth, underwire bras are often hand-washed or machine-washed on delicate cycle. Bra wash bags, usually zippered mesh pouches, can also be used to protect bras and prevent the underwire from separating from the bra during machine washing.

A metallic underwire is a thin strip of metal, usually with a nylon coating at both ends.

Metals used include steel and nickel titanium, a shape memory alloy.
