A variety of traditional costumes have been developed in Asia due to different natural and cultural environments and they are still worn by people in many areas. Traditional costumes in Asia have been formed under the influence of various ideologies, as well as technology and social structure. Three Asian religions(Buddhism, Hinduism and Islam), which have undeniably strong influence on traditional Asian cultures, have great effects on the styles of traditional costume in each region of Asia. The purpose of this study is to compare the characteristics and aesthetic values of traditional Asian costumes. To do this, the author used images of traditional costumes, which were taken in person by the author, in each region of Asia as reference. Unlike the traditional costumes in the West, which expose the body shape, traditional Asian costumes have nonstructural features in construction, form and wearing rules. They are also decorated with religious symbols and other ornaments, which is different from functional and non-decorative modern clothes. Each traditional Asian costume has unique characteristics. The costume under the influence of Buddhism shows the beauty of concealment that features trans-spatiality and abundant silhouette. On the other hand, the Hindu costume shows the beauty of symbolization represented by very colorful and complex ornaments, while costume in the Islam regions shows the beauty of restraint with clothes that wrap up the body in accordance with its strict religious discipline. Asian religions also represent philosophy, culture as well as an ethnic group. They have influenced entire Asian cultures including the arts, aesthetics and social structure and decided the style of costumes.
