The announcement comes at the start of London Sustainability Week and just days before People Tree opens its largest concession at the new Whole Foods Market in Kensington, London. In her previous role as Topshop brand director, Shepherdson's team brought People Tree into Topshop as its first ethical fashion brand.
Shepherdson said: 'People Tree is an incredible company, completely committed to producing good quality fair trade clothing. I have been very impressed by the team since I met them and am delighted to be able to use some of my expertise to help them to build the business.'
People Tree founder Safia Minney said: 'Having Jane at People Tree feels better than winning any award. Producers will hugely benefit from her practical help working with myself and the People Tree design team. Together with an experienced and a dynamic board I really look forward to addressing the barriers that prevent more people from benefiting from fair trade.'
At the weekend, Shepherdson also made a thinly veiled attack on her former employer Topshop, which has done much to drive down the cost of clothes and warned of an 'impending backlash' against fast fashion.
She said it was 'getting a bit boring' for people to find their wardrobes full of 'cheap rubbish. We should always question if something is very, very cheap and think that if you, the consumer, aren't paying for it, then someone, somewhere down the line is paying.'
