Abstract: This invention provides a wig having means for adjustment of the cap size of the wig for fitment to individual users and to reduce the stock numbers necessary to be carried by retailers to fit the variety of head sizes and still provide a full range of hair colors. The adjustment means can be an engageable strip of material to engage along the ribbon of a machine-made wig cap by engaging at the connection points of the ribbon and wefts of hair. The circumferential band of the wig may also be adjusted through the provision of such items as hook and eye fasteners.
