The emerging technologies and the resulting innovative material approaches give rise to new potentials in the field of textile and fashion design and allow the development of creative products through the formation of new perspectives. Intelligent textiles are materials that respond to these stimuli when they are interfered with external influences such as force, temperature, heat, light, chemical reactions, electricity, and magnetic. In the development of wearable systems, the integration of information and communication technologies into a garment or fabric is the most important goal. In this study, about design, engineering, science and technology interdisciplinary collaborative or interdisciplinary electronic textiles, smart textiles, clothes with nanotechnology codes; The concept of fashion intertwined with technology, original application project and current fashion design issues were mentioned. A flexible led and sensor caftan was designed within the scope of the study. The unique design of the kaftan, the grandeur of the selected fabrics and the motifs used for ornaments are highly effective. From this point of view, the T-shape in the Ottoman kaftans in terms of model kaftan, which the author designed from this point, is similar in terms of being brit in front and long-flashy arms. On the other hand, the modern line that the kaftan has to carry in order to conform to the ceremonies in which it is worn in today's conditions is seen in the original design. The product design, in which technology and design are applied together, is revealed.
