Abstract: Garment supporting devices and garment hangers are disclosed. One garment supporting device for attaching to a garment hanger comprises a shoulder receiving section operable to conform to a shoulder region of a garment when hung on the garment hanger. By being attachable to a conventional garment hanger, the garment supporting device effectively alters the dimensions of the hanger to accommodate the dimensions of the garment to be supported, especially its shoulder regions. Adapting the shoulder receiving section to conform to the shoulder region of a garment enables the same device to be applied to a conventional hanger in order to support garments having a range of differing sizes. Conforming to the shoulder region increases support in this region and reduces the likelihood of creating deformations therein.
