Katharine Hamnett’s bold slogan tees made her an ’80s icon, and now they’re back on the fashion front line at H&M. Katharine has teamed up with the high-street fashion brand tocreate a limited-edition T-shirt for Climate Week (12-18 March). Modelled by celebs Zara Martin, Sunday Girl,Roisin Murphy and Brit indie band The Vaccines, the timeless tees – which also happen to be low-carbon and are made from 100% organic cotton – bear the slogan ‘Save The Future’ and cost just £9.99. With 25% of profits going to the Environmental Justice Foundation’s climate refugees campaign, celeb approval and a designer name tag, we couldn’t think of a more covetable way to score some charitable brownie points.
