The fashion industry consists of four levels: raw material production, mainly fibers and textiles, but also leather and fur; Production of fashion products by designers, manufacturers, contractors, etc.; Retail sales; And all forms of advertising and promotion. These layers include a number of separate but interdependent divisions, all of which are dedicated to meeting consumer demand for clothing and enabling players in the industry to be profitable. LED lighting performance clothing is a key industry in the fashion industry.

Textile design and production, most fashion is made of textiles. The partial automation of the spinning and weaving of wool, cotton, and other natural fibers was one of the first achievements of the Industrial Revolution in the 18th century. In the 21st century, these processes are highly automated and carried out by high-speed machines controlled by computers. A large sector of the textile industry produces fabrics for use in clothing. Use natural fibers (such as wool, cotton, silk and linen) and synthetic fibers (such as nylon, acrylic and polyester). The growing interest in sustainable fashion (or "eco-fashion") has led to greater use of environmentally friendly fibres such as cannabis. High-tech synthetic fibers have characteristics such as moisture absorption and perspiration (such as Coolmax), anti-fouling (such as 303 high-tech fabric protection), heat preservation or heat dissipation, fire protection, weapon protection (such as Kevlar), cold protection (such as Thinsulate), ultraviolet radiation (Solarweave) and so on. Fabrics are produced by dyeing, weaving, printing and other production and finishing processes, and have a wide range of application prospects. Together with fashion forecasters, textile manufacturers prepare well in advance of the garment production cycle to produce fabrics that predict the colors, textures and other qualities that consumers want.

The next stage of production involves the assembly of garments. In this regard, technological innovations, including the development of computer-guided machinery, have led to the automation of certain stages of garment assembly. However, the basic process of sewing is still labor-intensive. This puts unstoppable pressure on garment manufacturers to find low-wage environments for factory sites, where issues of industrial safety and worker exploitation often arise. New York City's fashion industry was dominated by sweatshops located on the Lower East Side until the Triangle Shirtwaist Factory fire of 1911 led to greater industry unionization and industry regulation in the United States. By the end of the 20th century, China, with its low labor costs and disciplined workforce, had become the world's largest clothing producer.

The assembled garment goes through various processes collectively known as "finishing". "These include adding decorative elements (embroidery, beading); Buttons, buttonholes, hooks, zippers and other fasteners; Hem and cuffs; As well as brand labels and other labels (usually required by law) indicating fiber content, laundry instructions, and origin. The finished garment is then pressed and packaged for shipment.
