The hat on the back of the upper jacket in Scythian, in of northern region surrounding the Black Sea, is described as a typical woolen hood, but until now has been overlooked in Korean costume studies. The purpose of this study is to analyze the hat on the upper jacket in Scythians and to recognize the meaning of the hat. A further purpose is to complete the basic framework of research concerning the Scythian costume by adding the part that was overlooked previously As for the research method, we collected literature, previous research results, the exhibition catalog, and the related artifacts for analysis. The literature was collected at the German Archaeological Research Institute. The analysis of artifacts was based on data collected by the researchers at the Heremitage Museum in Russia and data was taken by the staff of the Heremitage Museum. The conclusions of this study are as follows: Among the artifacts in the northern region of the Black Sea, it was perviously believed that Scythians status was signified by the wearing of hat-tops. Regardless of age, warriors and knights all wore upper jackets with hats, so it appears that the people who are active wore upper jackets with hats. On the other hand, it was assumed that the royal family, who wore ornamented, colorful, and decorative hats were not observed to have worn upper jackets with hats, and therefore did not require a hat. Therefore, it is considered that the hat in the Scythian society was a costume element emphasizing practicality, not necessarily a class symbol.

This paper investigates the formative features and the historical meaning of the Korean dress collection held in the Museum of Archaeology and Anthropology in Cambridge. The Museum holds a total of eleven items of koran dresses that were donated by two anthropologists in the first half of the twentieth century. Male dresses consist of a white cotton jacket (Jeogori), a under-vest (Deungbaeja) made of light wisteria rings, a headband (Manggeon) made of horsehair, a broad brimmed top hat (Gat) made of black horsehair gauze, an oilskin cover (Galmo) drawn over the hat in wet weather, and a hemispherical hat box (Gatjib). Female dresses comprise a pink silk jacket (Jeogori), a blue silk skirt (Chima) with pleats, a pair of woman's white cotton trousers (Sokgot), a black silk cap (Jobawi) decorated with pink tassels and imitation pearls, and a pair of green and magenta silk shoes (Danghye) with leather soles and metal rivets. Theses Korean dresses show what the western anthropologists had interests in. When collectors collect the folk objects, they thought much of the specificity of shape and material, the esthetic appreciation, and the representation of daily life. In terms of the value as the historical materials in the history of Korean dress, the under-vest of wisteria, the hat box, and the female dresses are worth paying attention to. The under-vest is one that was produced in earlier time among the remaining under-vests. The hat box represents that the hat belonged to the merchant classes. The female dress items show daily dresses worn by women of higher classes of the society in the 1920s.

The purpose of this study is to analyze the formative relationship between clothes and hat with the works by Philip Treacy, the designer who raised hats to one of important fashion accessories. The method to analyze the relationship between clothes and hats was the formative analysis by Marian L. Davis and Marilyn R. Delong. The results suggest that clothes and hat had an organic relationship, and a hat style was changed with formative elements of clothes. Clothes and hats by Philip Treacy were analysed in the aspects of Form, Color, Material, and Decoration. As a result, hats by Philip Treacy were mainly designed by the relationship between whole types without a closed line and showed geometric and formative forms, similarly harmonized with clothes. To highlight hats, the achromatic colors such as black and gray were used. Besides clothes and hats were coordinated by the same colors, but contrary colors were used to express a strong image. Felt or straw materials maily used to express a formative and fixed form were well matched with smooth, opaque, and lusterless materials such as wool. Also when transparent materials were used for hats, lace was used for clothes. A hat made of acrylic was matched with clothes made of glossy vinyl coating materials. Decoration was mainly removed but if used, feather decoration was added to clothes.

Najang was the central Seori, affiliated to the Ministry of War during the Joseon dynasty. The objective of this study is to research the existing authentic Najang costumes from the late-Joseon dynasty by examining factors, such as the composition of the costume, size, and method of creation, and attempt to replicate it. The Leipzig Grassi Museum in Germany possesses an official uniform of Najang from the late-Joseon dynasty, and we visited the museum in May of 2013 to examine it for the study. Written records, or Uigwe, and other pictorial data from the Joseon Dynastry describe the Najang wearing black or navy clothing with white decoration and pointy hats. The most notable characteristic of the Najang uniform is that it has the cotton cords pattern. The hat has a brass ball attached, which was worn with the ball facing the front in the early Joseon Dynasty, and was worn facing the back in the later years. They usually wore black head cloths (Heuk-geon), but would attach feathers on the black hats (Heuk-rip) for special occasions. The Najang uniform preserved in the Leipsiz Grassi Muesim does not exist in Korea. It is made of cotton. The cotton cord pattern of the uniform of Najang was made using single-ply cords and double-ply cords. The hat worn by Najang is in a form of a cone that becomes narrower towards the top or is in a form with wide and open end. It was made of oiled paper covered with hemp, and two circular metal disks were attatched at the rear.
