For a hairdressing cape, a round opening is formed at the center of an upper region of at least a front cloth and a back cloth, and a collar portion with an overlapping portion is formed which is sewn to a peripheral edge of the round opening by folding an edge portion. A clasp is mounted to an inner end portion at one side of the overlapping portion of the collar portion, and a ladder tape is mounted from near an end portion at the other side of the collar portion to an upper region of the back cloth. By making the clasp be caught and fastened in an arbitrary position of the ladder tape, the overlapping portion of the collar portion is fastened.
