We have been hearing a lot about the sustainability of the fashion industry lately, it has become a fashionable research topic. Much of the research focuses on what information customers have, what influences their decision, and how they behave in a sustainable way when buying clothing or fashion items. The most conscious customers might be guided by the results of sustainability assessment systems for fashion companies. However, rating systems mostly focus on large companies. To our knowledge, there is no research that maps the views of small fashion companies on fashion rating systems. In this research, we used an interview method to examine how Hungarian fashion SMEs view sustainability assessment systems, how they would create their own system, and what future trends they expect in relation to these systems. The results show that SMEs consider good brand reputation more important than participating in a complex evaluation system.
