Portable clothes-drying assemblies are provided to allow travelers to quickly and easily dry articles of clothing. In one preferred embodiment of the invention, an assembly includes a specially configured garment bag from which a conventional hand held hair dryer is suspended. An adapter tube for directing hot air from the hair dryer into the interior of the garment bag is also provided. The adapter tube has a proximal end configured to sealingly engage the nozzle of the hair dryer and a distal end configured to sealingly engage an inlet formed at the bottom of the garment bag. In another preferred embodiment of the invention, the hair dryer is suspended from a horizontal rod, such as a closet rod, from which an article of clothing is also hung. An adapter assembly is also provided. The adapter assembly includes an adapter tube and a plurality of flexible distribution tubes that extend through the adapter tube and are configured to be inserted into the article of clothing. Each of the tubes has an proximal end configured to receive hot air from the hair dryer nozzle, a closed distal end, and an elongated intermediate portion made from either a porous material such as cloth or an apertured non-porous material that allows hot air to pass into the article of clothing.
