The authors study on the traditional textile production and the formal dress throuth the field research concerning the folk attitude toward dress style around the Mt. Kumo area. In this area, people produced and wove hemp, cotton, and silk except ramie. Because of poor production of raw materials, they produced textiles only for self-sufficiency. Every household dealt with dyeing on a small scale. In the past, people dyed cloth natually using plants as material. Natural dyeing, however, gradually changed into chemical one since the Japanese rule. The formal dresses, which people wore on particular occasions such as the hundredth day after child`s brith, the first birthday, and traditional holidays, were very meager due to poor living standards. People could not see the formal dresses with full decoration. Bride and bridegroom were the village-owned wedding dresses, and if they could not afford to, they simply put cloth on to remember the occasion. People around the Mt. Kumo area, however, provided fully-decorated shroud and ritual robes to the level of other better-off areas. It seemed to be the result of influence of deeprooted Confucianism in Gyungbuk province. This Phenomenon could be found in the folk dress style in other regions as well as the Mt. Kumo area in Gyungbuk province.
