<p>This article examines fashion practices within the liminal spaces of queer nightlife, such as occasional club nights, through the combined frameworks of autoethnography and femme theory. In investigating the intersections of gender, body and dress, I ask: How do liminal environments enable individuals to construct, explore, and express temporary identities through various modes of self-fashioning? To this end, I employ autoethnography as both a research method and a mode of writing, foregrounding my personal experience as a critical site for analyzing the affective, embodied, and aesthetic dimensions of gender vis-à-vis fashion. Within such experimental and transformative settings, I argue for dressing up as a practice that unsettles the gender binary in favor of excess, artifice and play. Drawing on ethnographic observations of costumes and fashion styles at a themed birthday party in Antwerp in 2018, this study demonstrates how liminal spaces cultivate unruly dress practices. By integrating recent scholarship on nightlife, it also situates these queer liminal spaces as dynamic arenas in which linear narratives of identity are suspended, enabling individuals to pursue unfixed modes of self-discovery. In doing so, I call attention to autoethnography as a queer method for examining the performative construction of identity, showing how fashion produces pleasure and resists the boredom of heteronormative life.</p>
