Abstract: A waist adjustment mechanism for a garment enables the waist size of the garment to be easily and conveniently adjusted to accommodate the extensive range of waist sizes among individuals. The waist adjustment feature consists of a series of opposed fastening elements disposed along the interior surface of the waistband. Engagement of select ones of the opposed fastening elements reduces the waist of the garment to the desired size. When used in connection with a pair of trousers, the trousers may optionally be provided with adjustable ankle portions which facilitate the wearer in putting his foot through the ankle openings.
