PROBLEM TO BE SOLVED: To provide an easily producible Kimono (Japanese dress) or Obi (sash) having light weight and high safety comprising the separation of a light source from the body and the absence of heat-generation and emitting brilliant color light by the irradiation with long-wavelength ultraviolet rays of 300-405 nm wavelength (so-called black light) to visualize the pattern. SOLUTION: A pattern designed on a woven fabric made of natural fiber, semi-synthetic fiber or synthetic fiber free from fluorescent dye is dyed, coated or printed with a dye containing an inorganic fluorescent color material composed of a metal oxide or sulfide as a crystal matrix and additives or coadditives such as rare earth metals or other metals and further containing other agents, diluents, hardeners, etc., with a brush, spray, etc. When the dye is irradiated with long-wavelength ultraviolet rays, the light is absorbed to and reflected from the crystal matrix to excite the fluorescent material and emit fluorescence without generating heat and a brilliantly colored pattern is developed on the cloth by the generated fluorescent light.
