The degree of involvement was known to shape the types of decision- process behavior of consumers. The types of information search would be influenced according to the degree of involvement. The purpose of this study was to find out the fashion information sources used in clothing purchase, and to clarify the interrelationship of clothing involvement and information sources. The middle and high school girls in Seoul were the subjects of the study. The information sources were classified into three types; marketer-oriented, internal and personal sources. Fashion informations spreaded by mass media were the most diversely used by teens. Among fashion information sources, ‘my own thoughts and experiences’ was counted as the most important one. And ‘interior and display of the shop’ was more important than the other marketer-oriented informations. Clothing involvement in the aspect of pleasure/symbol showed meaningful correlation with the information of ‘street fashion’, but in the aspect of fashion consciousness, ‘fashion of movie stars and celebrities’was the most significant information source. It seemed that ‘fashion articles in the magazines’ was used to reduce perceived risk in clothing purchase.
