A postoperative bilateral augmentation mammaplasty brassiere for use by women with augmented breasts is disclosed. The brassiere provides a support cup shaped to mimic a spherically shaped breast implant. The brassiere further provides an underwire within the construction of the brassiere, the underwire having an arcuate portion to mimic the round base of an augmented breast. A connector is provided between two support cups, each with an associated underwire, such that the distance between proximal ends of the underwires is established for the comfort of the wearer and the attractive appearance of the brassiere.
