In the case of Ankia bhaona, shimmering white costumes are worn by the large orchestra of musicians. The most striking character is that of the Sutradhara or the stage manager dressed in a white long-sleeved coat with a full, gathered skirt and wearing a white turban and elaborate ornaments. Leading characters wear colorful costumes and crowns, and sometimes masks are used to portray characters like Jatayu, Hanuman, Asuras, etc.

Mask making or Mukha Shilpa is an exclusive art practiced in a few Satras in Majuli. These masks were explicitly used during the performances of Ankia Bhaonas based on Ramayana, Mahabharata, and Bhagvata.

Characters like Hanuman, Raavan, Demons, Deities, and various animals were made, which were usually difficult to portray using makeup and costumes. These traditional masks can be of three types which are Su Mukha, Lutukai Mukha, and Mukh Mukha. The process of mask making is a very elaborate process, which may take up to two weeks. Following tradition, these masks are made of a woven bamboo frame for the structure and cow dung and clay for the features. The colors used to decorate these masks are obtained from organic sources like plants and minerals. However, nowadays, the artisans have started making masks with other decorative motifs on a commercial basis.
