Answer:
The technological development that revolutionized costume design in the past few generations is the computer-aided design (CAD) software.
Step-by-step explanation:
It allows costume designers to create and visualize their designs in a digital format, which can be easily modified and shared with other members of the production team. This technology has made the design process faster, more efficient, and more accurate, allowing designers to experiment with different styles, colors, and fabrics without having to create physical prototypes. It has also enabled designers to create more complex and intricate designs that would have been difficult or impossible to achieve by hand.
