Digitalization and the emergence of online video platforms changed the way people communicate and made new marketing opportunities. As mobile short-form video has unique characteristics, more people tend to consume and produce diverse content in the digital environment. The purpose of this study aims to better understand the influence of short-form videos from a fashion marketing standpoint and delineate the driving factors through story types. Specifically, by adopting common traits of short-form video content and story types based on Greimas’ narrative theory, this study explores customers’ intention toward fashion purchases and electronic word of mouth. In this context, this paper contributes to activating short-form video content as a tool to promote fashion brands and products but also opening up the possibility to further study short-form videos.
