Fashion designers must anticipate trends, select fabrics, and produce designs at affordable prices. They create original designs using elements like color, silhouette, and texture based on principles of design such as proportion and balance. The apparel production process involves basic decisions, design concepts, sales analysis, presentation, orders, and manufacturing. Haute couture is custom-made by hand while prêt-à-porter is mass produced. Women's sizing varies by figure type and age while men's uses standardized dual measurements.
