These blue Haider Ackermann cotton tapered trousers with belted detail feature belt loops, side pockets, back pockets and a central zip fly. As the famously rock 'n' roll frontman of Coldplay, Chris Martin, once advised: "You gotta wear the right trousers if you're gonna be a rock star." Sure, Chris. We'll just blame it upon a rush of blood to the head. Rock stardom aside, it would be wise to team these Haider Ackermann trousers with Ann Demeulemeester and M. Cohen.
