Abstract: An inner bust control portion of a swimsuit includes an elasticized fabric band that completely encircles the chest. A stretchy elastic horizontal strip is attached at its upper margin, and another at its lower margin, so that the band is pulled up against the chest. Two vertical elastic strips, one at the side of each breast extends from upper to lower horizontal elastic strips. At least one midline vertical elastic strip separates the breasts so that pockets are formed within the fabric band bounded by the elastic strips. The upper margin of the inner bust control portion is attached to the upper margin of the outer fabric of the swimsuit. In an alternative embodiment of the invention, the midline vertical elastic strip or strips are replaced by a drawstring.
