Topshop and Beyoncé Knowles have unveiled further details of their collaboration - introducing new activewear and athleisure brand, Ivy Park.

The range, first announced in October 2014, is available April 14 and includes leggings, crop tops, sweatshirts and jackets. Knowles commented 'When I'm working and rehearsing I live in my work out clothes but I didn't feel there was an athletic brand that spoke to me. My goal with Ivy Park is to push the boundaries of athletic wear and to support and inspire women who understand that beauty is more than your physical appearance'.
