This chapter explores how immersive technologies are applied across specific fashion product categories—apparel, accessories, and footwear—each characterized by distinct interaction dynamics, visual requirements, and psychological implications. By classifying fashion products, the chapter offers a more granular understanding of how XR solutions are integrated and optimized across segments. Apparel applications focus on virtual fitting rooms, avatar personalization, and confidence in size selection. Accessories—such as bags, jewelry, and eyewear—emphasize visual fidelity, material rendering, and gesture-based interaction. Footwear implementations prioritize AR-based VTO and customization, with increasing use of AI and 3D photogrammetry. The chapter draws on a wide range of empirical studies and design experiments to highlight key affordances and limitations in XR adoption, such as realism, usability, and emotional engagement. It also discusses cross-category approaches, including fully IVR stores. By organizing the literature according to product type, this chapter provides an analytical framework for evaluating XR’s effectiveness across fashion retail domains. The findings support the development of tailored, product-sensitive immersive experiences and offer strategic insights for researchers, designers, and practitioners working to enhance consumer interaction, personalization, and brand engagement in digital fashion environments.
