Abstract: The invention comprises a removeable and adjustable rack for mounting on a fixed garment hook inside the body compartment of a motor vehicle to increase garment hanging capacity. It includes a base plate which has an opening for hanging on a fixed garment hook and has opposing lateral side edges. The base plate has wing plates pivotably connected to the opposing lateral side edges. The wing plates can be pivotably adjusted to abut against the inside surface of the body compartment to stabilize the mounting of the base plate on the fixed garment hook. A hanger arm projects from the base plate to support plural garment hangers.
