An apparatus for steaming a garment comprising an expandable enclosure having a wall circumscribing a hollow space therein, the hollow space accessible through a re-closeable opening in the wall. A clothes hanging element and stretch element contained within the hollow space, the clothes hanging element for holding the garment and the stretch element for stretching the garment. A steam generator connected to provide steam to the hollow space. The steam generator has a water reservoir chamber and a steam chamber with a partition there between. At least one pair of electrodes is arranged within the steam chamber to provide an electric current that resistively heats a source of water to create steam. A water communication port in the partition allows water to pass from the water reservoir chamber to the steam chamber in a manner that self-regulates the amount of steam generated.
