Ivy Park, the athleisure collaboration between Sir Philip Green and Beyoncé, will launch on April 14 across 12 retailers in 50 countries.

The joint-venture will be sold in Arcadia’s Topshop in addition to JD Sports, Net-a-Porter, Nordstrom, Selfridges and Zalando in addition to Hudson’s Bay, Glue Store, Myer, Namshi, The Iconic and Zalora.

Beyoncé said: “Sir Philip has created some amazing collaborations but I wanted a partnership and a stand-alone brand. My goal with Ivy Park is to push the boundaries of athletic wear.”

Green added that he believed that the spring/summer collection was “just the beginning” of the Ivy Park journey.

The athleisure market has developed rapidly in recent years, with many retailers cashing in on the trend.
