The ethical and environmentally-friendly clothing line Edun - founded by U2 frontman Bono and his wife Ali Hewson in 1995 - began as a simple t-shirt and denim collection; it has since expanded to include higher-end ready-to-wear but remains fiercely committed to it’s initial mission of encouraging trade with Africa.  Glen Baxter sat down with co-founder Ali Hewson while she was in Toronto for a trunk show at Holt Renfrew.
