To solve the problem that a conventional reflective sash hardly reflects lateral light from an automobile at night.

A reflective sash 100 is provided, including a three-dimensional part 2 provided in a part of the sash 1 corresponding to the front and back of a human body, wherein the three-dimensional part has a curved face 5 having a semi-circular cross section. On the surface of the curved face 5, a reflective material 4 is disposed as curved in a width direction. When the reflective sash 100 is put over the shoulder, the reflective sash can reflect light from an automobile or the like even when the front side of the body is irradiated with light of an automobile and also can reflect light incident in an oblique or lateral direction, as the reflective material 4 is curved in the width direction of the sash. Thereby, a person wearing the reflective sash 100 is easily recognized from a driver of an automobile or the like.
