Forget the rich and the famous, it's Diet Coke that has our designers chomping at the bit to dress these days. Following on from Patricia Field's limited edition bottles for the fizzy sensation, are these new designs from Roberto Cavalli, to mark the start of Milan Fashion Week. Only 300,000 will be made of the three variations, and in true Cavalli style, they are pretty flash. Dressed to the lid in animal print, I'm betting these beauties will leave Cavalli's usual crew (J.Lo, Victoria Beckham & co.) clamouring to get a taste.
