The Trench Coat design project, inspired by the 2025 border conflict between Thailand and Cambodia, transforms the “symbol of war” into “fashion for reconciliation.” It incorporates the Luk Kaew pattern from Si Sa Ket province, reinterpreted in a pixel art print that creates a digital-like effect on a Trench Coat derived from military uniform structures. The design can be understood through five conceptual dimensions: Sustainable Fashion, Cultural Sustainability, Synthetic Aesthetic, Design for Peace, and Speculative Fashion. In Sustainable Fashion, the adaptation of the Luk Kaew pattern into contemporary design promotes social sustainability and community identity (Fletcher & Tham, 2019; Gwilt, 2020). The integration with Thai military camouflage uses existing materials, redesigning and upcycling symbols of violence into fashion aesthetics (Balsiger, 2016). The Trench Coat, originally a symbol of mass production, is reinterpreted within community craftsmanship, aligning with slow fashion principles that value meaningful production and narrative (Barnard, 2023; Riegels Melchior & Svensson, 2014). Cultural Sustainability is addressed by preserving intangible local heritage through fashion (Tarlo, 1996). Applying the Luk Kaew pattern to a universal silhouette enables local textiles to reach global fashion platforms, connecting local identity with a global language (Moisander & Valtonen, 2006; Barnard, 2023; Manzini, 2015). The Synthetic Aesthetic emerges through pixel art interpretation, producing a digitally-inspired beauty that bridges past and present. Although handcrafted, it resembles digital textures, showing that “synthetic” signifies reinterpretation and creative novelty rather than artificial materials (Fry, 2009). This challenges binaries such as natural vs. synthetic and traditional vs. contemporary, creating a symbolic world merging reality and artifice (Barnard, 2023; Irwin, 2015; Manzini, 2015). In this context, macramé was incorporated into the hem of the Trench Coat as an additional design layer. The knotting technique of macramé symbolises entanglement and conflict, yet when carefully structured into patterns, the knots become a metaphor of reconciliation and harmony. Aesthetically, the repetitive knots form grid- or pixel-like structures, extending the pixel art reinterpretation of the Luk Kaew pattern into a three-dimensional textile effect. This hybridisation between digital aesthetics and craft aesthetics reinforces the project’s Synthetic Aesthetic dimension. For Design for Peace, the fusion of military camouflage and Luk Kaew pattern positions the garment as a medium for social dialogue, linking historical memory, beauty, and reconciliation (Thabet et al., 2025; Manzini, 2015; Irwin, 2015; Gwilt, 2020). The macramé knots further enrich this peace narrative, symbolising how multiple conflicts, once tied together, can be transformed into structures of beauty and resilience. Finally, in Speculative Fashion, the narrative of “war–peace–synthetic beauty” creates an imaginative space, enabling the Trench Coat to function as both a wearable and a speculative object, questioning the future of borderland societies, fashion, and cross-cultural relations (Fry, 2009). Within this frame, macramé becomes a speculative metaphor: each knot is a conflict that cannot be easily undone, yet when interconnected, the knots collectively form strength, continuity, and the possibility of a reimagined social fabric. Overall, the Trench Coat transcends clothing to become a symbolic space, merging past and future, local and global, violence and beauty, and nature and digitality. The integration of macramé into its construction amplifies this symbolism, turning the garment into a hybrid of digital and craft aesthetics while embodying sustainability, cultural heritage, aesthetic experimentation, and social dialogue.
