The structure and operation of supply networks have received considerable attention from both the business community and academic researchers in the last two decades as the pace of globalisation has accelerated. Supply networks in the international clothing industry have developed and evolved significantly over that period. This paper reviews different ways to categorise supply networks and notes their limitations in providing insights on the structure and operation of networks in the contemporary global clothing industry. Leading retailers and major clothing brand owners influence strongly how such networks operate. Given the limitations of existing generic classifications, a new classification of clothing supply networks is presented based on extensive empirical evidence from the Sri Lankan clothing industry. The relevance of the findings for network design and management are noted. This study of supply networks in the international clothing industry provides much potential for further research, particularly in globally dispersed industries.
