Underwires are the semi-circular boundaries around the cup of a bra. Note that this particular style is discontinued. The heavy gauge is our new style. Note that not all sizes are available in this style. The sizes in the drop down are the only sizes available. The nylon coating helps prevent rust, but excessive stress on wires can cause the coating to crack. The colored ends indicate the center front of the bra. Underwires are made from spring carbon steel and can be molded to fit the body with a little work.
These are traditional regular underwires that fit the average of commercially made bras. Not all manufacturers use recommended sizes and styles, so please check the measurements against any wires you are replacing. If you are making a custom bra for the first time, I recommend purchasing 3 wires - one that is recommended for your size, one size up and one size down. You can return any unused wire packages.
