Many women have worn underwire bras most of their lives. There are a few things to take into consideration when fitting an underwire nursing bra. Make sure that the wire is not pressing on any breast tissue, especially under the arm. The wire should fit well back behind your breast tissue. If a wire is pressing on the breast, it can cause plugged ducts.
Mommy Gear also offers many softcup styles that support and lift as well as an underwire. If you are not sure if you have breast tissue under the arm, it might be best to consider a softcup nursing bra.
