The purpose of this study is to examine the fashion design applying to the hoop, which have become various since 1980. To do this, this study is investigated the origin and the changes of the hoop historically, then classified its types, and finally analyze the collections from 1980 to 2003. The hoop was appeared on the late 15th century. Then in the mid 16th century, bell-shaped farthingale was prevailed, followed by drum-shaped wheel farthingale and hausse-cul in England and France. In the 17th century, slim silhouette was popular, so that the hoop declined gradually. In the 18th century, panier and panier double were introduced which is to make side-expanded skirt silhouette. In the 19th century, crinoline and bustle were created. The hoops applied to modern collections are used various materials, techniques, and forms. It is a main item of historicism which appeared in the trend of post-modernism and the phenomenon of applying underwear to an outer garment like corset. The hoop is adapted into three ways: only with the frame of hoop, wearing a skirt with some parts of the frame exposed on purpose, and wearing a skirt on the frame, thus not showing the frame. Thus, it is thought that wearing a hoop as a frame is used an element of recreation of past fashion, at the same time it was affected by historicism which is a branch of post-modernism. Applying the hoop as an outer garment may be affected by eroticism which changed underwear into an outer wear in postmodernism and deconstructivism.
