For men, the main chest piece/robe is called a "Chamanto" which is basically a type of poncho, made of wool, but the interesting design is that it is worn both side! It is reversible, a dark color to be worn during the day and then reversed to the light color side for night time!
For women, they wear what is called a "Pollera Skirt" which is a long colorful fabric that has many underskirt garments and wear a blouse with ruffles and jewelry on their chest.
However, in the south of Chile, the traditional outfits are close to the Argentinians, where they wear "gauchos", normally worn by huasos and huasas which are the Chilean version of cowboys and cowgirls. The gauchos are large pants that wave while moving, they cover the legs without being tight except at the belt level. It is the main traditional clothing of Argentina.
Nowadays the folkloric dresses of Chile are mainly used in artistic performances as well as dances and some bull-games and shows. Some of the remote villages in the south still have gauchos. The folkloric clothes of a country tells a lot about its people, and for Chile, it shows a lively country with a spirit of fun, dance, and family attachment as described by its natives.
