The purpose of the thesis is to offer a view of the Fashion Industry and its economic, environmental, and social impact. In particular, its Supply Chain will be investigated. The Fashion Industry went through a deep transformation that started at the end of the 20th century and changed the pace that had been one of the pillars of the sector: the fixed calendar of fashion shows has been ousted by a growing number of collections, characterized by cheap and low-quality clothes. One of the main factors that fuelled this huge change has been globalization, that led to the relocation of a big share of the Fashion Industry outside Europe, mainly to Asian countries, favoured by less stringent Labour and Environmental Laws.
