Mekhela chador is a traditional Assamese dress. There are two main pieces of cloth that are draped around the body.
The bottom portion, draped from the waist downwards, is called the mekhela. It is in the form of a sarong, a very wide cylinder of cloth that is folded into pleats to fit around the waist and tucked in. The folds are to the right, as opposed to the pleats in the Nivi style of the saree.
The top portion of the two-piece dress, called the chador, is a long length of cloth that has one end tucked into the upper portion of the mekhela and the rest draped over and around the rest of the body.
The wearing style is like a "saree" without it being a saree itself
