A board is vertically mountable to a wall or door and features an upwards extending support structure to which a garment hanger support bracket is attached. The garment hanger support bracket is itself vertically adjustable to permit hangers to be supported relatively higher or lower with respect to the board. A vertical adjustment of the bracket consequently allows respectively longer or shorter garments to be hung in a substantially centered position in front of the board. In addition the garment hanger support bracket features a plurality of vertically spaced hanger support recesses which allow a garment to be vertically relocated during a steaming operation without the need to vertically readjust the garment hanger support bracket itself. This latter feature permits a garment to be vertically shifted to bring wrinkles in upper and lower portions of the garment to a convenient working height.
