paper-bag waistbands means: The paper-bag waistbands can be a contradiction. They are both looser and made with extra fabric. Think of a sweet-filled paper bag that is closed. Turn this fabric into fabric by adding a belt. The paper-bag waistlines are versatile and can either be high or low, reflecting Katherine Hepburn’s spirit. The name of the paper-bags comes from their gathering method and fabric above the belt hooks. (in Fashion Dictionary)
