Abstract Purpose - The purpose of this master thesis is to research the Generation Y’s online purchase intention for fashion items while creating and using a customised avatar. Overall, the objective is to create a better understanding of this technology’s potential, formulate managerial implications for fashion businesses and strengthen business viability.

Design/Methodology/Approach - The research approach of this study is deductive, whereby hypotheses derive from the Decomposed Theory of Planned Behaviour. After secondary data is reviewed, a single quantitative data collection is applied, thus following a mono-method. This primary data is gathered virtually through a self-administered online questionnaire. A total number of 205 qualified responses from the Generation Y are statistically analysed using a structural equation modelling. This descriptive research design is chosen to conduct the relationships between the latent variables and the behavioural intention.

Findings - The empirical findings reveal, that the attitude, subjective norm and perceived behavioural control significantly and positively influence the Generation Y’s online purchase intention to create and use a customised avatar. While the attitude, with the behavioural belief of perceived usefulness specifically, shows the strongest influence on the behavioural intention, the research sample also sees a fit to all technology facilitating conditions, affecting the perceived behavioural control. In comparison to this, the subjective norm influences the behavioural intention in a weaker manner, whereby the research sample is influenced more by external than interpersonal factors.

Implications - To enlarge the Generation Y’s online fashion purchase intention while creating and using a customised avatar, fashion marketers are advised to highlight and improve the usefulness of the technology. Fashion businesses are recommended to implement interactive digital platforms, by employing influencer marketing, in order to endorse and promote the brand awareness in regard to the technology.

Originality/Value - This master thesis addresses the online purchase intention for fashion items while creating and using a customised avatar from a commercial perspective. Where prior literature findings lack the link to managerial implications, this study examines the Generation Y’s behavioural intention towards this technology. The Generation Y has an immense and increasing purchasing power, which is accompanied with technical skills, thus making them crucial for the market success of online fashion businesses. Therefore, the authors examine the technology's commercial potential and encompass the whole fashion industry.
