IntroductionFast fashion provides the latest fashion trends along with agile response to consumer demand with reasonable prices (Choi, 2014;Jin, Chang, Matthews, & Gupta, 2012). Fast fashion's target market is large population of mobile young people. Due to the fact that fast fashion has become a key feature of the global fashion industry over the last decade (Choi, 2014), there is phenomenal growth in the availability of fast fashion brands in international markets. With the aggressive international expansion of fast fashion retailers, young consumers in Taiwan are attracted to fast fashion's "hot" products, featuring updated looks, greater variety, and limited editions.This study aims to empirically investigate the factors affecting consumer's fast fashion brand loyalty from an international perspective by examining Taiwanese college students' perceptions of and loyalty towards fast fashion. Based on our extensive literature review, we proposed a research model (Figure 1) which examines the factors affecting consumer's brand loyalty in the fast fashion context. The research model encompasses six hypotheses that are illustrated in the model. We hypothesize that consumer's perceptions of fast fashion including brand awareness, perceived quality, perceived value, brand personality, organizational associations, and brand uniqueness affect consumer's brand loyalty.
