The purpose of this study is to explore if the clothing shopping orientation[CSO] of consumers differs between the two types of preferred store when they purchase casual wears. A total of 413 answers from male and female consumers in their twenties were used for the analysis. The types of preferred store were grouped by the brand fame. Department stores, brand agencies/sales branches, and outlets constituted well-known brand store group, and shopping malls, no brand street stores, and discount stores constituted unknown brand store group. The results are as follows. First, there were no significant differences in CSO dimensions except well known brand oriented dimension between groups. Second, each group showed proper fitness for CSO structure model. Third, the relationships among dimensions within structure model were significantly different between groups. These mean that though it looks there are no differences between groups at the level of each dimension, but there are differences in the view of specific relationships among dimensions. Therefore, store managers must consider the complex CSO structure for marketing strategy development.
