A panty brief for holding a diaper comprises at least one holding part (10). According to the invention the holding part is produced integrally with the front piece and/or the back piece. The holding part (10) may consist of threads (11), which are not knitted together with the remainder of the bag side (1), and which are placed symmetrically and will hold a diaper symmetrically in relation to leg openings (5, 6). The panty brief is made in endless lengths and is shown as it appears after the production with the wrong side turned out. Accordingly, after the production and severing the only operations required are to turn the inside out and to place the diaper in the holding part (10). Hereby, a panty brief is achieved which gives a secure holding of a diaper and which may be produced in endless lengths without the need of any after-fashioning.
