Abstract: The present invention provides a garment liner for protecting clothing comprising an elongated strip of absorbent material having a face surface, a back surface, a pair of opposed longitudinal edges and a pair of opposed tapered ends. The garment liner includes an adhesive disposed on the back surface for securing the liner to a garment. A backing strip is removably secured to the adhesive to preserve the adhesive until the user is prepared to secure the liner to the garment. The garment liner further includes at least one of the tapered ends having a plurality of perforations which can be torn to remove segments of the liner so that the garment liner can be custom-sized to fit any variety of collar sizes which are commercially available.
