The design process from design concept to final production takes many months. Researching current fashion trends and making predictions of future trends is the first step in creating the design. Some fashion designers do their own research while others depend on trend reports published by fashion industry trade groups. Trend reports let you know what styles, colors and fabrics will be popular for a certain season in the near future. Textile manufacturers use these trend reports to design fabrics and patterns while fashion designers begin to sketch designs. Designers then visit manufacturers or trade shows to get samples of fabrics and decide which fabrics to use with what designs.
