Fast fashion brands provide consumers with constantly available opportunities to update,not only their wardrobes, but themselves. As our identities have become a constant projectto work on, consumption of fast fashion involves the possibilities of trial and error ofpersonal development. Consumers are predisposed to shape or change their personalities byusing brands as additional traits. This is conceptualized as Brand Engagement in SelfConcept (BESC) to explain how consumers build and express identities. Even if FastFashion is recognized to make trends available for a democratized audience who continuallyevolve temporary identities, it is a limited researched area where Brand Engagement in SelfConcept (BESC) is addressed. As this tendency to involve brands in consumers' self-concept(BESC) is defined as an individual trait to be measured, there is still no qualitative researchto our knowledge that provides deeper insights of how this subjective objective is displayedor affecting the pre-purchase stage within the context of fast fashion.The purpose of this degree project is to develop a deeper understanding of consumers'tendency to incorporate brands as a part of their self-concept and how brand engagement inself-concept (BESC) influences the pre-purchase stage in the decision-making process inthe context of fast fashion. In order to fulfil this purpose, a qualitative study wasimplemented by applying semi-structured interviews with six individuals with the propertyof being consumers of generation Z. Pursuant to previous research that states how thesegeneral tendencies of BESC varies amongst individuals, we were able to identify diversegeneral tendencies in the empirical findings of involving brands in self-concept.These various indications of involvements were represented by the identified themesreflecting how the consumers are applying the silent, but expressive languages of clothing,regarding their representation of themselves through what they wear, awareness of trendsand the extent of purchasing.With regard to these identified indications of involving brands in self-concept to differentextent, our empirical findings resulted in themes, addressing how the pre-purchase stagewas influenced in the context of fast fashion. Our results show how the pre-purchase stageis initiated by recognizing a need or opportunity congruent with the self-concept.Additionally, as information is searched, this stage is influenced by the involvement ofbrands in the self-concept by the identified themes: inspiration, coincidence and familiarity.As the evaluation of alternatives is made, the themes of “considerations to social context”and “the fit” are identified as being influenced by BESC. The consumers' self-concept hasbeen found to be defining the extent of influence, in terms of composing the reference tocompare fast fashion brand personalities with. Consequently, we draw the conclusion thatthe negative associations of fast fashion limited the involvement of fast fashion brands inthe self-concept as these personalities were considered unappealing by representing cheap,quick compliance, low quality and unethical values. Our results demonstrate how the needfor social consistency and approval motivates young consumers to involve fast fashionbrands in their self-concept. This is contradicting displayed in terms of buying the basicassortments with the absence of fast-moving trends.
