Which of the following is NOT one of the key elements of fashion design?

Branding is primarily focused on creating a strong identity and image for a fashion line or designer, which is distinct from the fundamental elements that directly relate to the design itself. The key elements of fashion design—color, texture, and line—play a critical role in shaping the aesthetics and overall appeal of garments.

Color influences how a design is perceived emotionally and visually, while texture affects how a fabric feels and drapes, adding depth and richness to an outfit. Line refers to the silhouette and shapes created by the design, which can evoke different styles and trends. All these elements work together to form the core of fashion design, while branding encompasses a broader marketing strategy that surrounds the design but does not directly affect its creation. Therefore, recognizing branding as separate from the core design elements clarifies why it does not fit into the list of key elements of fashion design.
