an article of daily clothing traditionally worn by Polynesians and other Oceanic peoples. It consists of a single rectangular cloth worn as a skirt. [...]
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.[...]
[It] 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.
