Lava-lava

A lavalava, also known as an 'ie, short for 'ie lavalava, is an article of daily clothing traditionally worn by Polynesians and other Oceanic peoples. It consists of a single rectangular cloth worn as a skirt. The term lavalava is both singular and plural in the Samoan language.

Today the fashion remains common in Samoa, American Samoa, Tonga and parts of Melanesia and Micronesia. It is worn by men and women in uses from school uniforms to business attire with a suit jacket and tie. Many people of Oceanic ethnicity wear the lavalava as an expression of cultural identity and for comfort within expatriate communities, especially in the United States (notably Hawaii, Alaska, California, Washington, and Utah), Australia, and New Zealand.

The lavalava is secured around the waist by an overhand knotting of the upper corners of the cloth; women often tuck the loose ends into the waistband, while men usually allow them to hang in front. Women generally wear ankle-length lavalava while men's wraps often extend to the knee or mid-calf depending on the activity or occasion.

Prior to the arrival of Europeans in the Pacific Ocean, the most prestigious lavalava were made by wrapping the body in a 'ie toga with fine mats (finely woven textiles of pandanus leaves) or siapo (tapa cloth) pounded from paper mulberry or wild hibiscus bark. The Samoans also created lavalava from traditional materials such as flower petals, leaves, feathers and seashells tied to a wrap-around backing of plaited plant fibers.
