This is the underwire version of our most popular bra. It is smooth, clean, and perfect under tees and sexy tops – all tops – a perfect seamless underwire nursing bra. The cups are full coverage cups. Each cup has a 3-position adjustment to drop the cup for customized fit (move the cup to the highest position after nursing, move the cup to a lower position as the breast becomes heavier between nursings). 83% tactel nylon /17% LYCRA - this strong, supportive fabric is very soft, with great strength, to support the breasts as they change during the day before and after nursing.
