Buying used clothes is far from a new phenomenon; a certain segment of every new generation of teens and 20-somethings invariably gets drawn into spending time combing through the racks at thrift shops. But in the last decade, the emergence of online, peer-to-peer fashion resale marketplaces has turned the act of purchasing and selling used clothes into a much more mainstream activity. Even before the pandemic, the growing interest in sustainability and the circular economy had helped increase interest in this brand of grassroots-driven ecommerce. Once Covid-19 began, more and more people forced to stay at home found themselves going through their closets to see what potential merchandise they had to offer. Vestiaire Collective is one of the top start-ups helping to drive this trend, and its CEO, Max Bittner, joins us to talk about the challenges and opportunities in the thriving space.
