A shoulder brace is provided with two support members each attached at one of its ends to a belt of adjustable length worn about the torso of the user. The support members extend diagonally upwardly across opposite sides of the body whereby their opposite ends are positioned outwardly and above the user's torso. The support members pass through a sleeve adapted to rest on the shoulder of an arm to be supported by the brace. The respective opposite ends of the support members are joined to a support bar from which an arm-receiving sleeve is suspended. By adjustment of the lengths of the support members and by selective bending of said members, the shoulder brace is adapted to fit different body sizes and to suspend the user's arm in a desired position.
