Common elements include cape-like draped sleeve panels, loose open structures, lightweight fabrics such as chiffon, tulle, or silk, and frequent use in gowns, dresses, and high-fashion garments. The overall style emphasizes sophistication, glamour, and dynamic movement, creating a regal and theatrical fashion look.
