Tennis champ Serena Williams is no stranger to a bit of competition. Hell, ankles don't break themselves. So it'll come as no surprise that she's taken on Katy Perry in this now cult D&G leopard-print dress. While Pezza opted for the yellow frock and got there first, adding rock-chick peep-toes and bundles of necklaces, Serena's a fan of tha tan version - and casts, as it goes. Fashville's gone WILD for D&G leopard print this summer and we love both their looks - but who takes home the fashion trophy?
