The lungi is a type of sarong that originated in the South Asia. The lungi, which usually multicoloured, is a men's skirt usually tied around the lower waist below the navel. it can be worn as casual wear and night wear, in places and climates where the heat and humidity increase sweating, and make it unpleasant or uncomfortable to wear closed and tight clothes such as trousers. Design They are especially worn in hot regions. There are also cheaper "open" lungis, in identical dimensions but not sewn into a tube shape. The standard adult lungi is in height and in length, when open. Children's lungis are approximately two-thirds of this size. They are normally woven from cotton and come in a variety of designs and colors. Silk lungis are used for ceremonial purposes such as weddings. The most common styles are solid-colored and plaid, reflecting the relative ease and cost-effectiveness of producing these patterns on a power loom. Blue is particularly popular, since it fades to pleasant tones in contrast to other colors. Regardless of the design or color, lungis are often lined at the top and bottom with a black/white stripe containing reinforced weaving to prevent fraying. Usage Depending on local tradition, lungis can be worn by men or, more rarely, women. They are tied or fastened in various ways and can be used in different cultural activities, ranging from normal daily life to elaborate wedding ceremonies. For daily purposes, a simple "double twist" knot is most popular, where two points in the upper edge of lungi are brought together and twisted around twice, with the ends tucked in at the waist. However, it is also common for wearers to simply tie a double "pretzel knot" from 2 points on the upper border, which produces a more secure knot. The lungi's length can also be adjusted, for example, by tucking in the lungi at the waist to make it resemble a short skirt. This is mostly used for labourers who have to work for a long time under a hot sun. Regional variations India In India, the customs of wearing lungis vary by state. It can be worn with or without the traditional unsewn kaupinam or modern sewn langot, both of which are types of traditional loincloth undergarments. In Kerala, the lungi is generally colourful and available in various designs, and is worn by both men and women. It
