Individual’s existential ambivalence has according to Jacques Derrida, one of the foremost proponents of post-structuralism, led to a continuous demand for structure (Cooper, 1989). Categories, used as structural tools, are however often hierarchically organized, where one category is more preferable than the other, also referred to as binary oppositions. Alternative categories and/ or references will appear when adopting a deconstruction process, which is crucial in order to invoke change and development (Cooper, 1989; Markkula et al., 2011; Marion, 2006). The aim of present research is trying to identify if Derrida’s theory of undecidable transfer of features (Agger, 1991; Cooper, 1989; Livingston, 2010; Bates, 2005) is applicable in fashion, more specifically fast- and slow fashion, and if the two categories are susceptible to a merge. Deconstructionism and Derrida’s theory of undecidable was furthermore applied as the theoretical framework throughout the study. Present research has been executed with an interpretive methodological approach and through a poststructural epistemological outlook (Hudson & Ozanne, 1988; Eriksson & Kovalainen, 2016). Data was derived through two focus group interviews, involving seven informants at a time, with Autodriving as a visual research tool (Heisley & Levy, 1991) and open-ended questions as a complementing instrument (Eriksson & Kovalainen, 2016). A thematic analysis was furthermore applied when revisiting the data and analysing its content. The findings finally suggest that a merge between fast- and slow fashion is executable, which furthermore also legitimises Derrida’s theory of undecidability. This study has however only begun the deconstruction process and does therefore encourage future researchers to continue investigating the theory of undecidability (Agger, 1991; Cooper, 1989; Livingston, 2010; Bates, 2005) not only in fashion, but also within other institutions.
