The fashion and costume design industry is rapidly evolving through the integration of computational tools, requiring systematic models that balance creativity with technical accuracy. This paper presents a compact mathematical framework that unifies three critical components parametric pattern generation, physics-based cloth simulation, and generative design to support modern fashion product development. The proposed model begins with a parametric geometric representation, which enables accurate and flexible pattern construction adaptable to diverse body measurements and design specifications. This mathematical layer allows for automated size grading and precise adjustment of silhouettes, thus minimizing manual intervention. The second component introduces a physics-informed simulation, where fabric behavior is modeled using measurable parameters such as elasticity, drape, and tensile strength. This ensures that virtual garments reflect real-world performance, improving both fitting accuracy and material optimization. The third component incorporates a generative aesthetic design layer, which draws upon stylistic priors and computational creativity to accelerate the exploration of new forms, textures, and patterns. Together, these three modules establish an end-to-end digital pipeline that integrates rapid ideation, virtual fitting, manufacturability assessment, and sustainability checks. Implementation strategies are briefly outlined, focusing on algorithmic adaptability and integration with existing computer-aided design (CAD) environments. Validation strategies suggest experimental prototyping using digital twins and virtual fashion platforms to evaluate model efficiency. Key advantages of the framework include reduction in material wastage during sampling, accelerated iteration cycles from concept to prototype, and enhanced systematic control over both aesthetic and functional constraints. By embedding mathematics into fashion workflows, the framework provides a scalable pathway for researchers, technologists, and designers seeking to align artistic innovation with efficiency, sustainability, and precision in contemporary costume and fashion technology
