Fashion industry emissions, resource use, and waste are attracting increasing consumer and government attention, with broad agreement that a new approach is required along the supply chain. Following the COVID-19 pandemic, a move to digitalisation facilitated an accelerating interest in digital applications, including immersive technologies such as augmented and virtual reality. This systematic literature review explores the intersecting topics of fashion, immersive technologies, and sustainability to determine the trends, examine the solutions offered, and discuss the implications of immersive technologies for sustainability. Four resources were consulted (Scholar, SCOPUS, WOS, and ProQuest), resulting in 74 articles for the review. Grey literature was included due to the currency of the topic and gaps in the available academic literature. The findings highlight immersive technology uses in the fashion industry, which are part of a move towards sustainability. These technologies are used to reduce online returns, educate consumers, reduce waste in design and manufacture, and remove the need for physical items. However, issues include high energy costs, consumer reluctance, and skill shortages. Results suggest future research and industry discussions should focus on empirical studies to measure the sustainability impact of immersive technologies, monitor technology diffusion and uptake, and measure the industry skills gap.
