The focus of this qualitative case study was to explore the intricate relationship between Coastal Fante Festival performance costumes, sculptural objects, and the indigenous knowledge system and practices of the coastal dwellers, who reside in the central coastal regions of Ghana. To explore the social constructs of Coastal Fante Festival performance costumes and sculptural objects comprehensively, this study employed a multidisciplinary approach, combining ethnography, archival research, and artisan collaboration in the geographical context of Winneba and Cape Coast. The unstructured interview and direct observation were the instrumentations used for the data collection. The interpretative phenomenological analysis (IPA) and visual data analysis tools garnered from sixteen (16) research participants using purposive (expert) and simple random sampling techniques allowed for a holistic understanding of the cultural, historical, and societal dimensions of these costumes and sculptural objects within the Central region coastal community, shedding light on their role as living embodiments of indigenous knowledge and cultural practice. The study revealed that these costumes hold profound cultural significance, symbolizing historical events, social identities, behaviour, codes and spiritual connections within the community. As a result of these social constructs, enculturation and inculturation were achieved, materialising cultural identity, defining mood (attitude), enhancing performer welfare, and addressing issues of history were addressed through performance costumes and sculptural objects. The generation should see these costumes with sculptural objects as a living embodiment of indigenous knowledge and cultural practice, enriching the understanding of Fante culture and its significance in a global context.
