Fashion-based social enterprises (FSEs) are social enterprises (SEs) that advance a social mission through the sale of fashion products and the encouragement of ethical fashion consumption. As part of the broader ecosystem supporting social entrepreneurship, many FSEs utilise third-party certification and accreditation systems to provide their consumers with tangible assurances regarding their sustainable and ethical processes. However, while these systems can deliver some reassurances, they also come with their own challenges. For these small, often under-resourced businesses, the accreditation process can be costly and time-consuming. For fashion consumers, the proliferation of certification labels can lead to increased confusion about the validity of ethical claims. This chapter explores how ethical accreditations function as part of the policy and regulatory ecosystem supporting FSEs in Australia. Based on a series of roundtable focus groups and interviews with Australian academics, government representatives, accreditation bodies and FSEs, it argues that while certifications may not significantly alter business practices for FSEs, they provide a model for shaping broader regulatory frameworks. As policy tools, these systems can potentially strengthen institutional support for FSEs by certifying what these businesses are already doing in ways that assure consumers of the social impact their purchasing supports. The chapter concludes by considering ways in which policy interventions and accreditation systems could be reformed to reduce barriers and better support the ecosystem for FSEs, ensuring that these mechanisms are accessible and effective in promoting the ethical and sustainable practices necessary for a sustainable fashion future.
