As a fashion designer, you'll design clothing, footwear or accessories for consumers. You begin a design project by selecting a target market and researching trends. Then, you'll sketch design concepts, select materials, create prototypes and oversee production as your designs come to life. The entire design process can take up to two years. You may choose to design multiple types of products or only clothing, accessories or footwear. You may design for the mass market, create high fashion custom designs or design costumes for motion pictures.
