The mundu (Malayalam: മുണ്ട്; pronounced [muɳɖɨ]) is a garment worn around the waist in Kerala, the Tulunadu region, and the Maldive Islands. It is closely related to the dhoti, sarong, and lungi. In South Kanara, a district of Karnataka state, the Tulu speaking folk and Beary community also wear the mundu. It is normally woven in cotton and coloured white or cream. The colour is dependent on whether the cotton is bleached or unbleached. A kaddar mundu is made using handlooms. When unbleached, the mundu is called "neriyathu". In modern times, two types of mundu are prevalent - the single and the double. A single mundu is draped once around the waist, while the double is folded in half before draping. A mundu is usually starched before use.
A mundu usually has a line of comparatively thicker cloth woven into it near the border called the kara. The kara can be coloured and comes in various sizes. There are also double coloured and ornamental kara (a strip of colour at the end of the mundu). & Costumes Of Kerala.For more ceremonial occasions (like weddings), a mundu has a golden embroidery known as kasavu. The wearer highlights the 'kara' by carefully folding the end of the mundu. The kara generally appears on the right hand side of the person, though styles with the kara on the left side are prevalent. Unspoken rules of etiquette govern the way the mundu is worn. Men will often fold the garment in half to resemble a short skirt when working, cycling, etc., but it is considered disrespectful to speak to women or one's social superiors with the mundu folded up this way, revealing the legs from the knee down. When faced with such a social situation, the fold of the mundu is loosened with an imperceptible flick and it flutters down to cover the legs completely.
The 'melmundu' is an upper garment similar to the '[neriyathu]' that is worn by women; 'mundu' and 'melmundu' are part of the traditional Malayali costume worn by men.
