Abstract: A lightweight, substantially unpadded, comfortable, push-in underwire bra has, when worn by a female wearer, a front including a pair of cups. Each cup defines upper inner and outer portions, lower inner and outer portions, a top and a bottom, and is configured and dimensioned to hold substantially one breast of a female wearer. Each cup defines an underwire receiving channel extending downwardly from the cup upper outer portion and then inwardly across the cup bottom to the cup lower inner portion where the channel terminates. A single underwire-free channel extension connects the channels of the cups only at the lower inner portions thereof, the cups being connected at the front only by the channel extension, thereby to provide a deeply plunging cleavage and enable substantial independent motion of the cups relative to one another. For each cup, a thin, arcuate underwire is disposed in the channel and biases the cup upper outer portion inwardly.
