An incontinence article configured for use with an undergarment for absorbing urine leakage caused by stress incontinence. The article includes a base layer and a plurality of pleats extending from a top side of the base layer on each side of the base layer. The article is formed of a flexible and absorbent fabric. The bottom end of the base layer is sealed to the bottom end of the pleats on either side of the base layer. Adhesive on the bottom of the base layer configures the article for adherence to the inside of an undergarment. When base layer is secured to an inside panel of the undergarment, the article expands, via the plurality of pleats, to the contours of the undergarment body of a user wearing the undergarment.
