Clothing was an important aspect in Inca society. Just looking at the dress of a person, status of that person in that society can be readily perceived. Though their costume initially was typical of that of all the Andean and coastal peoples, afterward they excelled on it. Archaeologist collected full information on Inca clothing as in imperial days it was enforced on the conquered populations. Grave finds and paints especially on pottery vessels provide enormous information on Inca costume.
General Trends
Naturally more and warmer clothing was worn in the highlands than on the coast. In the earliest periods the inhabitants of the former region had only wool, the latter only had cotton, but at a very early time trade made both materials available everywhere. These textile fibers, wool from the highlands and cotton from the coast- especially the former- were practically state monopolies and were regularly distributed to the people. Clothing everywhere consisted of woven or knitted textiles, and these were always worn whole, never cut or tailored; they were held together by large metal pins. The garments of the common people were of rather coarse textiles.
Inca Emperor.
Sapa Inca wore each cloth for only once. Afterwards the worn clothes were burnt. So you know, they need to supply lots of cloth for Sapa Inca. As you know "chosen women" were the ones who prepared clothes for Sapa Inca. So they had to remain busy on this purpose. Only the Inca could wear a headdress with his special fringe of gold and feathers. His headdress was of different kind: round his head was wreathed a turban of many colored folds, called the llautu, with a tasseled fringe, like that worn by the prince, but of a scarlet color, while two feathers of a rare and curious bird, called the coraquenque, placed upright in it, were the distinguishing insignia of royalty. His coat was covered with jewels and pieces of turquoise. Sapa Inca wore gold and jewelries on different parts of his body. He wore heavy gold shoulder pads and heavy gold bracelets and earrings. His earrings were so heavy that they pulled his earlobes down until they rested on his shoulder pads. His shoes were made of leather and fur. He wore a royal shield and a royal badge. The shield on his chest was engraved with a picture of the sun god and the badge was made of hummingbird feathers, framed with gold.
