It also illustrates how a region’s labour laws and historical relationships with Western clients can embed the importance of ethical behaviour alongside modern cost and lead time cutting demands.

It highlights the fact that for fashion businesses, it’s a challenge to incorporate sustainability when the critical success factors are cost efficiency and effectiveness.
