Based on the discussion of the concept,origin,and form of three-dimensional structure aesthetics,this paper studies the application of three-dimensional structure aesthetics in modern fashion design from three aspects:the design of the modeling mode in three-dimensional structure,the applica-tion of the material in three-dimensional structure,and the reconstruction of the color elements.It is be-lieved that from the perspective of three-dimensional structural aesthetics,modern clothing design should make breakthroughs in the following aspects:expanding the channels of conceptual sources and injecting modern contextual elements;innovating structural processing methods by leveraging diverse material ele-ments;emphasizing the significance of color matching,and highlight the value in humanistic emotions.
