Abstract: A swimsuit having an inner liner of stretchable and resilient fabric for encasing at least a portion of a person's torso, including the abdomen, hips and rear areas; at least one control panel bonded to the inner liner for restricting the stretching of the inner liner fabric and controlling bulging at a desired area of the encased torso; and an outer swimsuit fabric covering over the inner liner. The control panels are preferably located on the abdomen and both upper rear hip areas of the inner liner and have significantly less stretch than the inner liner fabric alone. The panels may be made of soft, flexible synthetic fabric or plastic laminated to either the interior or exterior surface of the inner liner.
