In sustainable fashion research, upcycled fashion design has often been examined from the perspectives of material circulation, resource conservation, and brand strategy, while the mechanisms of form generation and aesthetic significance have remained insufficiently discussed. From the perspective of deconstructivist aesthetics, this paper examines ten upcycling-related collections released by Marine Serre between 2018 and 2025, specifically analyzing the relationships between structure, material, surface, making practices, and upcycled expression. The study first reviews the theoretical intersections between deconstructivist aesthetics and upcycled design, arguing that the two are not identical but form a conditional relationship through the design logic of "dismantling-reconfiguration-re-signification." Second, based on an initial observational sample of 497 garments, the study identifies 108 upcycling-related pieces as the formal analytical sample and establishes control samples with weaker deconstructivist features. Finally, through formal analysis and qualitative content analysis, the study distinguishes strong, moderate, and weak levels of deconstructivist aesthetic expression. The findings show that some of Marine Serre's upcycled works display clear deconstructivist tendencies through pattern-piece reconstruction, juxtaposition of heterogeneous materials, visible traces of patchwork, and the re-signification of used objects. However, this tendency is not uniformly present. Upcycled design demonstrates strong deconstructivist aesthetic features only when the origins of used objects, structural reconfiguration, making process, and transformation of meaning are visualized, thereby unsettling conventional notions of garment completeness, unity, and material hierarchy. Based on these findings, this paper proposes a four-dimensional analytical framework for aesthetic research on upcycled fashion design.
