Consumer trust is a key prerequisite to building a strong relationship between an organisation and its clients. The fashion industry has not only been a source of clothing over the centuries. However, it has also been a great source of employment and a major contributor to the world’s growing economy. This places a high demand on the need for its sustainability in the twenty-first century, where consumers not only purchase products but also pay critical attention to the producer’s trustworthiness. A sure means of increasing patronage of the fashion industry for sustainability is to make customers believe in the industry’s operations and services. Several studies have focused on increasing productivity in the fashion industry, placing little emphasis on the need to build consumer trust in its operations. This chapter focuses on exploring the appropriate measures that the fashion industry should adopt to win consumer trust and ensure sustainability within the sector. It examines the concepts of sustainability, attitude, and consumer trust, as well as critical strategies for building effective consumer trust to promote the sustainability agenda.
