The purpose of this paper is to explore barriers and opportunities for business models based on the ideas of collaborative consumption within the fashion industry. The analysis is based on a multiple-case study of Scandinavian fashion libraries – a new, clothes-sharing concept that has emerged as a fashion niche within the last decade. It is concluded that fashion libraries offers interesting perspectives, e.g. by allowing people to experiment with styles without having to pay the full cost and becoming a meeting place for young designers and end consumers. However, at present fashion libraries remain a small-scale phenomenon with difficulties reaching the mainstream market, not least due to limited financial and human resources as well as conventional fashion consumption patterns.
