First, in Korea, all fashion orientations gave positive effects on attitude toward luxury brands, and especially it has a significant relation with factors affecting luxury brand consumption, so when luxury enterprises establish a marketing strategy for Koreans, they need to refer to fashion orientation intensively. Second, as a result of analyzing the relation between fashion orientation and purchasing behavior, it was found that fashion interest is an important factor affecting luxury brand purchasing behaviors, in both Japan and Korea. Third, Japanese luxury brand enterprises need to focus on consumers who prefer standard goods. while Korean enterprises need to focus on consumers who prefer specific brands.
