Novak Djokovic and his wife Jelena organized the Novak Djokovic Foundation gala dinner presented by Giorgio Armani at Castello Sforzesco on Tuesday evening, attracting a stunning number of high-profile guests, including WTA players Serena Williams and Flavia Pennetta.
The world No.2 Williams, who made a girls' trip to Italy with two friends, dazzled in a black velvet minidress featuring elegant silk panels and skater hemline. Interestingly, Jelena Djokovic opted for a similar dress design and it's hard to tell who wore it better.
