Abstract: The present disclosure is directed to an improved waist band stay for women's garments comprised of a substantially rectangular, thin, one-piece, laterally free-riding, readily insertable and removable, strip of polypropylene plastic having substantially rounded corners at its leading end with a hanger opening centrally located in the vicinity of said leading end and indicia (markings) located thereon along the length thereof, e.g., calibrated in centimeters and/or inches (and portions thereof) to indicate length and make it simple for the user to cut the stay to the length appropriate for, viz., slightly less than e.g., from about 0.125 inch to about 1.0 inch less than, the wearer's waist measurement. The premeasured and marked strips usually range in width from about 1/2 to 13/4 inches and in lengths from about 30 to about 48 inches with a substantially uniform thickness of about 0.02" to about 0.04" plus or minus 10%.
