Recent studies have examined the correlation between erotic capital and luxury brands, which is essential to social success. However, limitations of such research have been noted due to the ambiguity of the concept and measurement of erotic capital. Therefore, in this study, we clarify the components of erotic capital and develop measurement tools to study the expansion of the base of luxury brands. To this end, a survey targeted 200 consumers who had purchased luxury brands within six months. The results of this study show that the attraction value of individuals and expected social success increases purchases of luxury products. This study suggests that marketers of luxury brands based on traditional values should reflect the concept of erotic capital for product planning, promotion, and marketing to expand the consumer base.
