Fashion designers are individuals who create and design clothing, accessories, and footwear. They are responsible for conceptualizing and creating new styles and trends, often working with fabrics, colors, and patterns to bring their designs to life. Models, on the other hand, are individuals who showcase and promote the designs created by fashion designers. They work with photographers, stylists, and designers to present the latest fashion collections through runway shows, photo shoots, and other promotional events.
