The clothing sector, once embracing the use of emerging digital technologies, such as artificial intelligence, big data, blockchain, and the Internet of Things (IoT), can offer a new range of products and, most importantly, integrate new services in association with its clothes. Also, new technologies in the fashion industry can help to implement Sustainability solutions and to establish clothing as a service. Once this is already a reality in the apparel industry and a topic in the academic literature, this article aims to investigate through a bibliographic review what is the state of the art of smart clothing and emerging technologies in the clothing sector and what are the relationships with the provision of services through clothing. The results indicate the possibility of products with positive impacts both in people´s lives and for the environment, but it alerts to the risks of ecological impacts and issues in personal data safety if not designed properly.
