Sarong or Pareo? What's the difference?

Sometimes we use the word pareo instead of sarong...The pāreu or pareo is the Cook Islands and Tahitian word for a wraparound skirt. Originally it was used only to refer to women's skirts, as men wore a loincloth, called a maro. Nowadays the term is applied to any piece of cloth worn wrapped around the body, worn by males or females. It is related to the Malay sarong, Sāmoan lavalava, Tongan tupenu and other such garments of the Pacific Islands such as the islands of Hawaiʻi, Marquesas, Aotearoa, and Fiji.
