The traditional costume of the Andaman and Nicobar Islands, an archipelago in the Bay of Bengal, is known as the "Pukari" or "Pattu." It is a brightly colored garment worn by the indigenous communities of the islands, primarily the Nicobarese and the Shompen tribes.

The Pukari consists of a knee-length tunic or shirt for men, which is usually made of cotton or silk. It is adorned with intricate handwoven designs and patterns, often depicting local flora and fauna. The tunic is paired with loose-fitting trousers or shorts, made from the same material and decorated with similar motifs.

For women, the traditional costume consists of a colorful wrap-around skirt called a "Lava" or "Pareo," which is tied at the waist. The lava is usually made of cotton or silk and features vibrant patterns and designs. Women also wear a matching blouse or top, which is typically sleeveless or short-sleeved.

Both men and women accessorize their traditional costumes with handmade jewelry, such as necklaces, bracelets, and earrings, often crafted from shells, beads, or natural materials found on the islands. Additionally, they may wear headgear or headbands adorned with feathers, flowers, or other decorative elements.

The traditional costume of the Andaman and Nicobar Islands reflects the rich cultural heritage of the indigenous communities inhabiting the region. It is worn during festivals, cultural events, and special occasions, showcasing the pride and identity of the local people.
