The evolution of the fashion industry from traditional bi-annual seasons to the rapid 52 micro-season model has significantly impacted sustainability. Fast fashion brands continuously push new trends, leading to overproduction, textile waste, and an increased carbon footprint. The predominance of synthetic materials, particularly polyester, amplifies environmental concerns through non-biodegradable waste and microplastic pollution. The socio-economic effects of micro-seasons extend to labor exploitation in developing nations, where garment workers face unsafe working conditions, unfair wages, and the erosion of labor rights. Additionally, the growth of fast fashion has encouraged impulsive buying habits, especially among Gen Z, influenced by social media trends and endorsements from influencers. This trend-driven consumer culture promotes disposable fashion and undermines traditional craftsmanship with cheap, machine-made alternatives. Addressing these challenges requires a shift toward sustainable design, responsible sourcing, and circular business models. Consumer behavior, industry accountability, and policy enforcement play crucial roles in mitigating the negative impacts of micro-seasons. This paper critically examines the impact of micro-seasons on sustainability and explores strategies to foster a more ethical and environmentally responsible fashion industry.
