Lei niho palaoa: A Lei niho palaoa is a Hawaiian neck ornament traditionally worn by "aliʻi" (chiefs) of both sexes.  The 19th century examples are most commonly made of a whale tooth carved into a hook-shape suspended by plaited human hair.  The symbolism is not known; it may represent a tongue that speaks the law, or may represent a vessel for "mana" (inherited virtue).  Precontact lei niho palaoa were less than two inches in length, and were not only made of whale ivory, but also of shell, bone, wood, stone, and coral.  Sometimes, several of these smaller pendants were strung on twisted human hair.  The Bishop Museum has a lei niho palaoa with a hair bundle having a circumference of 7.5 inches.  It is made from a single eight-ply square braid cord, measuring 1,708 feet, looped back and forth over 1000 times on each side.

Wabash Confederacy: The Wabash Confederacy, also referred to as the Wabash Indians or the Wabash tribes, was a number of 18th century Native American villagers in the area of the Wabash River in what are now the U.S. states of Illinois, Indiana, and Ohio.  The Wabash Indians were primarily Weas and Piankashaws, but also included Kickapoos, Mascoutens, and others.  In that time and place, Native American tribes were not political units, and the villages along the Wabash were multi-tribal settlements with no centralized government.  The confederacy, then, was a loose alliance of influential village leaders (sometimes called headmen or chiefs).

Amasunzu: Amasunzu is an elaborate hairstyle traditionally worn by Rwandan men and unmarried women, with the hair styled into crests, frequently described as crescent-shaped.  The hairstyle indicated social status, and men who did not wear Amasunzu were looked on with suspicion until the 20th century.  The style was also worn by unmarried women after the age of 18–20 years, indicating that they are of marriageable age.

Dush-toh: A dush-toh, also spelled dush-too, dush-tooh, or dush-tuh, is a traditional Caddo hair ornament worn by girls and women during dances, particularly the Turkey Dance.

War bonnet: War bonnets (also called warbonnets or headdresses) are feathered headgear traditionally worn by male leaders of the American Plains Indians Nations who have earned a place of great respect in their tribe.  Originally they were sometimes worn into battle, but they are now primarily used for ceremonial occasions.  They are seen as items of great spiritual and political importance, only to be worn by those who have earned the right and honour through formal recognition by their People.

Vaddanam: Vaddanam is an ornament worn around waist typically in the south Indian territory.  It is traditionally worn during festival days and major family occasions like marriages as a status symbol in "south Indian".

Caddo: The Caddo Nation is a confederacy of several Southeastern Native American tribes.  Their ancestors historically inhabited much of what is now East Texas, Louisiana, and portions of southern Arkansas and Oklahoma.  In the early 19th century, Caddo people were forced to a reservation in Texas, then removed to Indian Territory in 1859.

Impact of Native American gaming: Impacts of Native American gaming can be positive or negative, depending on the tribe and its location.  In the 1970s, various Native American tribes took unprecedented action to initiate Native gaming enterprises.  In doing so, they created not only a series of legal struggles between the federal, state, and tribal governments but also a groundbreaking way to revitalize the Native American economy.  Native American gaming has grown from bingo parlors to high-stakes gaming and is surrounded by controversy on many different levels.  There are disputes concerning tribal sovereignty, negative effects of gaming, and a loss of Native American culture.  In the United States the Indian Gaming Regulatory Act was passed in 1988 in order to secure collaboration between the states and tribes and also in order for the federal government to oversee gaming operations.  Native American gaming has proven to be extremely lucrative for several tribes, but it has also been unsuccessful in some instances.  Native American gaming is contingent upon and only beneficial to its respective reservation.

Gamucha: Gamucha (also "gamocha" (ga=body, mocha=wipe), "gamchcha", "gamcha") is a thin, coarse, traditional cotton towel found in India, Bangladesh as well as various parts of South and Southeast Asia and is used to dry the body after bathing or wiping sweat.  Gamucha is the local term for a sweat towel.  It is often just worn on one side of the shoulder.  However its appearance varies from region to region.  Gamucha has been traditionally worn as scarf by male folks of Orissa which was mentioned in Oriya Mahabharata by Sarala Dasa.  Male villagers wear it as dhoti.  Children of tribal communities in Orissa wear gamucha until their adolescence after which they wear dhoti.  Weavers of traditional "tantubaya" or "jugi"community migrated from Bangladesh to Tripura and weavers of Orissa produce good quality gamucha.  Gamucha is most commonly found with check and striped patterns of red, orange or green.  Plain white gamchhas with coloured (embroidered or printed) borders from Orissa and Assam (for traditional Assamese Gamucha, see Gamosa) are local handicrafts, and may be worn around the neck with traditional Indian attire.  In western areas, gamucha is primarily made in red colour and are plain like cloth.  In southern India, gamucha is more coarse and are available in various dyes.  Even homemade lightweight fur towels are also popularly termed as gamchhas.  Gamucha are worn by the South Asian people, especially in the Indian states of Andhra Pradesh, Bihar, West Bengal, Jharkhand and the Purvanchal region, because they are not as thick as Western-style towels and better suited to the country's tropical, humid climate.  In Afghanistan they are also used and are commonly referred to as dismaal.  They may also be found in Central Asian, Middle Eastern and Turkish hamams as a traditional male loin cloth and towel worn during bathing and massage.

Koteka: The koteka, horim, or penis gourd is a penis sheath traditionally worn by native male inhabitants of some (mainly highland) ethnic groups in New Guinea to cover their genitals.  They are normally made from a dried-out gourd, "Lagenaria siceraria", although other species, such as "Nepenthes mirabilis", are also used.  They are held in place by a small loop of fiber attached to the base of the koteka and placed around the scrotum.  There is a secondary loop placed around the chest or abdomen and attached to the main body of the koteka.  Men choose kotekas similar to ones worn by other men in their cultural group.  For example, Yali men favour a long, thin koteka, which helps hold up the multiple rattan hoops worn around their waist.  Men from Tiom wear a double gourd, held up with a strip of cloth, and use the space between the two gourds for carrying small items such as money and tobacco.
