The drapery display hanger comprises a plurality of drapery arms and a support surface. The support surface can be easily and reversibly mounted to a pre-existing display fixture without the need for special hardware. The support surface can include brackets having opposing surfaces angled from vertical for ease of installation and protrusions for securing the support surfaces in place once installed. Additionally, the drapery arms can be reversibly attached to the support surface using attachment devices at the end of each arm. The attachment devices may include segments that are inserted into the holes in the support and then secured against the walls of the support for bearing the weight of drapery on the drapery arms. Sliding and pivoting functionality is also provided. The drapery arms are sized so that full-sized draperies can be displayed facing the customer and without compressing the drapery in the display.
