So Kate Moss is set to return to Topshop with a collection due out in April – poppy print dresses at the ready. And then there's H&M's forthcoming Isabel Marant collection coming out in November, too. Which previous high street/designer collaborations do we remember fondly - and which are the ongoing pairings that should never end?

When it's done well, that magic combination of elite design talent and high-street prices proves irresistible. H&M has the best track record of wooing big name designers, but Moss and Topshop had a certain special something (she may not have been a designer, but at the time she had the most envied and imitated personal style in the world). There was also Karl Lagerfeld's dramatic fall-out with H&M and Jil Sander's irresistibly chic work for Uniqlo (pictured right).
