A clip for hanging a skirt that can be attached to an existing hanger. The distance between clips can be freely adjusted to hang, skirts from small children's to large adult sizes without causing creases. The clip neither damages cloth of a skirt nor leaves marks on a skirt while preventing a skirt from slipping off a hanger. Furthermore, the clip for hanging a skirt is very small in volume and of low-cost. The clip for hanging a skirt includes a plate-like connecting piece (2), first and second pinching pieces (3) and (4) having smooth inside surfaces which are movably connected to both ends of the connecting piece (2) at positions under upper ends of the first and second pinching pieces, a vertical piece (5) downwardly extending from a center of the connecting piece (2) and having two protrusions (6) and (7) on a lower end portion of the vertical piece (5) each of the protrusions being directed to an inner side of each of the first and second pinching pieces (3 and 4), and a lock piece (8) foldably connected to an upper end of the first pinching piece (3). The lock piece (8) maintains the inside surfaces of the first and second pinching pieces (3 and 4) to be pressed toward the protrusions (6 and 7) by engaging the lock piece (8) with an upper end portion of the second pinching piece (4).
