The current research aims to shed light on consumer-brand relationship, adopting the self-determination theory as theoretical lens for defining the antecedents and the consequences of the Brand Engagement in Self Concept (Sprott, Czellar, & Spangenberg, 2009). The originality of the study stems in the contest of analysis, that is the international cosplayer community, given the extreme engagement manifestation of the actors of the community in comics characters. Thus, the goal of this study is to test a model previously proposed by Razmus, Jaroszyńska, & Palęga (2017) in a community of high engagement manifestations, that is the cosplayer community (e.g. dress-up as their own favourite character). Moreover, authors would like to introduce a novel variable that is the brand-self congruity (Aaker, 1997; Sirgy, 1982), able to influence the relationship between personal aspirations (Kasser and Ryan, 1993; 1996), brand engagement in self-concept, brand advocacy (Kim et al. 2001) and brand loyalty (Oliver, 1999).
