The black coat crafted from cotton was manufactured by the Mikir community, from the northeastern Indian state of Assam. This coat was used as an iconic combination of both practical and metaphoric uses by the men of the Mikir community for several generations. Such a coat has become a cultural representation, signifying the tribe's proficiencies in assorted textile handcrafts and weaving. The black coat comprised cotton material displaying patterns of woven geometric forms both from the front and back, just a little beneath the neckline. The geometry inlaid is close to the heart of the Mikir in their view of all things natural; deep down in nature embodying these sacred geometries is a spiritual quarter worthy of protecting for future generations to appreciate carrying on their heritage that dates back thousands or tens of thousands of years geographically in Assam.

Geometrical motifs typically signify the general condition of life and the insatiable interconnection between all beings as a central doctrine of the Mikir tribe. The black coat/trunk, being made of cotton, is meant to withstand wear. Moreover, such fabric is justly comfortable to shield the wearers in their daily existence of manifold climates of Assam. The simple version is engineered by stitching together two pieces of cloth, leaving some openings for the neck and arms and creating an ordinary but useful design. Cotton fringed, hanging long at the lower end of the coat, both decorates the garment and permits the coat to move with the wearer. The Mikir/Karbi males wear the black coat during various ceremonies, rituals, and festivals, thus symbolizing their cultural identity as Africans and masters of skilled weaving and fabric-making. This black cotton coat thus has more to do with presenting the people's rich heritage, skill, and affinity towards the surrounding environment.
