Givenchy by Riccardo Tisci presents a ‘Rottweiler’ print Wool Flannel Backpack for Fall 2011. The imagery matches up with a number of pieces in Givenchy forthcoming collection, including sweats, shorts and tees (check Selectism for looks). If you’ve got the ball, you can pre-order yours at Luisaviaroma. There’s also a solid black canvas version in the same shape, for those who are feeling a little less adventurous.
