This study is taken as the part of the cultural research on the Kaspian coastal region, which has a great significance as the start of human civilization and in the history of cultural exchange. This study is focused on the Achaemenid dynasty of the great Persian Empire that Iranians have established on the Parsa region, south of Iran on 6-4th century B.C. This research limits to the tribute-relief illustrated on the stairs of Apadana Palace in Persepolis during the age of Achaemenid dynasty. The objective of this research is classify and analyze Persians and its neighboring tribes, their dresses and the detailed elements of the dresses to complete the typology of the dresses in that period and use this to categorize the features of nomadic and agricultural tribes of costal areas of the Mediterranean Sea to Northern India and study the cultural exchange and its effects. Furthermore, we aim to use the above typology to revise the typology of the Korean traditional dresses that were formerly just sorted as a type of coat-trousers that classified as a nomadian Scythian dress type. The results of above analysis are as follows: The clothing of many tribes living in the coastal areas of Mediterranean Sea to the Northern India in the Achaemenid dynasty of Persia on 6th century B.C. shows that the typology of the dressings have close relationship with the region they live in. Such typology is displayed differently from tribes east and west of Iran. The tribes west of Iran showed characteristics of an agricultural tribe and the tribes east of Iran displayed features of a nomadic tribe. In addition, uniformed styles of dressing were displayed amongst many tribes sharing a common lineage. Such inference came from the fact that similar styles of dressings were identified not only in tribes east of Iran but also in tribes west of Iran.
