<![CDATA[The phenomenon of thrifting among Generation Z (Gen Z) presents a paradox between environmental preservation claims and the reality of consumptive behavior. While thrifting is perceived as an implementation of the circular economy, practically, it is often trapped in motives of signaling status (flexing) and hoarding, which exacerbates textile waste. This study aims to formulate a new consumption ethic termed "Eco-Sufism Consumption" to bridge the gap between lifestyle and ecological responsibility. This research employs a qualitative method with an interdisciplinary conceptual analysis framework, integrating Sociology of Consumption, Circular Economy, and Sufi Theology. The results reveal three main findings. First, sociologically, Gen Z's thrifting motives are dominated by sign value and simulacra, where second-hand goods are recommodified as social status symbols. Second, economically, Life Cycle Assessment (LCA) analysis validates that thrifting can reduce water footprints by up to 98% and carbon emissions by 90% compared to new production, yet this effectiveness relies on consumption volume. Third, theologically, the concepts of Zuhd (asceticism) and Qana’ah (contentment) serve as the primary controlling variables. The study concludes with a new ethical formulation: Ekp = Z x (Sos + Eko), asserting that spiritual consciousness (Zuhd) is the determining coefficient that validates the ethical value of social and economic actions. Without spiritual control, thrifting remains merely a destructive consumerist trend. This study contributes to sustainability and consumption studies by introducing a spiritually grounded ethical framework that integrates social, economic, and theological dimensions.]]>
