“…Summarizing, the challenges of fast fashion retailers are: (i) efficient just-in-time models (the delivery of goods to meet consumers demand with minimal inventory at the store), (ii) agile supply chains (shorter and more flexible demand driven supply chains), (iii) quick response (to consumer needs with new and fast available products), and (iv) demand chains (supply chains focused on customers' requirements) (Barnes and Lea-Grenwood, 2010;Zhang et al, 2017). Moreover, word-of-mouth communication (with emphasis on e-word-of-mouth), celebrity endorsement, new forms of advertising, with emphasis on social media like Facebook can positively influence the building and maintenance of brand-customer relationships for fast fashion brands, due to the positive effect of engagement and affective commitment facilitated by the social media (Barnes and Lea-Greenwood, 2010;Chang and Fan, 2017;Halvorsen et al, 2013). In particular, those two factors are considered as determinants of long-lasting relationships between consumers and fast fashion brands (Chang and Fan, 2017).…”
