Abstract: An exercise brassiere having an outer layer adapted to fit over the wearer's upper torso and shoulders and a coextensive inner layer adapted to fit over the front portion of the wearer's upper torso and shoulders. The inner layer and the outer layer are constructed of a lightweight, flexible two-way stretch fabric having a stretchability significantly greater in the horizontal direction than in the vertical direction to provide adequate and comfortable support to the wearer's breasts. The inner layer has cut into it a pair of apertures sized and positioned to receive the breasts of the wearer the apertures being covered by the outer layer. The apertures also provide support to the wearer's breasts and further provide for a natural, contoured appearance to the wearer's breasts.
