It’s no longer just cool to be ethical, it has become a necessity.

Or so says Dr Jem Bendell, who noted that once favourite brand of the stars - Dolce & Gabanna - was hardly a presence at this year’s Oscars.

Dr Bendell suggested that D&G had fallen from grace with the A-list because of alleged unethical supply chain issues. For example, last December, an Italian TV documentary 'Slaves of Luxury' had detailed cases of illegal Chinese immigrant labour in Italy allegedly making accessories for a number of brands, including D&G.

But perhaps the best example of the popularity of ethical fashion is the return of designer Katherine Hamnett to the fashion scene. Hamnett left the scene four years ago after she found it hard to push sustainable fashion. But today, as shoppers become more aware of ethical fashion, designers such as Hamnett are having the last laugh.

So supply chain directors, take note – as consumers grow more ethical, so must you.
