ENNowadays e-commerce is becoming an ever more popular source for shopping, which doesn’t have the downfalls of physical stores – long lines, health risks and time wasting. Companies, considering the rising popularity of e-commerce, are seeking to expand their internet store assortments, in hopes of better taking care of consumers demands. However, if the decisions to expand product assortments are rash, they can lead to choice overload, which negatively affects e-commerce user experience. Thus, the research problem is – how choice overload affects e-commerce user experience. In this research it was chosen to limit the scope of the empirical research and the subsequent solution design strictly towards the fashion sector of e-commerce. The object of the research is the effect of choice overload on e-commerce user experience.The aim of the paper – based on the theoretical analysis and research methodology, to conduct an empirical study about the impact of choice overload on e-commerce user experience, and to create project solutions, meant to reduce the negative effect of it. Scientific research methods used in this research are the following: a theoretical analysis of scientific sources (publications, books, and conference presentations), a quantitative case study, a consumer questionnaire survey, and a solution design approach. First, the paper focused primarily on analyzing the various concepts of choice overload and e-commerce user experience. Additionally, the theoretical analysis focused also on how choice overload affects e-commerce user experience. At the end, a theoretical model was introduced. Keywords: e-commerce, fashion sector, choice overload, user experience, hedonic user experience, pragmatic user experience.
