Abstract: A garment having an adjustable waist is provided. The adjustable garment includes a waist portion and an adjustment device. The adjustment device is disposed along a surface of the waist portion and includes a central receiving element and opposing fastening elements. The opposing fastening elements are positioned laterally along the waist portion at opposite sides thereof. Furthermore, the opposing fastening elements are spaced from the central receiving element and are configured to be selectively secured to the central receiving element. With this configuration, a user can quickly and conveniently alter a position of the opposing fastening elements relative to one another, and maintain this position via attachment to the central receiving element. As a result, the area or circumference defined by the waist portion is readily adjustable.
