Abstract: A midriff controlling undergarment includes an upper torso encircling portion and a lower torso encircling pants portion releasably connected together at a parting plane located approximately at the waist of the user. A plurality of circumferentially spaced apart snaps are on the adjacent edges of the upper and lower portions, releasably joining them together in overlapping relationship to shape and control the waist of the user and prevent midriff bulge. The snaps enable easy, one-hand attachment and release of the two portions, thus facilitating use by obese persons or persons suffering from other infirmities, such as blindness and the like.
