H&M, the world's second-biggest fashion retailer after Zara owner Inditex said in a statement it would launch Kenzo's H&M collections in around 250 stores worldwide and online in November.
Kenzo's apparel is known for its vivid colours and prints.
H&M has collaborated regularly with upmarket fashion houses and celebrities for more than a decade as a part of its marketing strategy, with partners ranging from designers Karl Lagerfeldt to Alexander Wang to football star David Beckham.
As opposed to H&M, Spain's Inditex spends little on advertising campaigns and does not do designer collaborations.
