Rihanna sported the pajama trend at the Japanese premiere of the movie 'Battleship'.
She wore an Emilio Pucci Fall 2012 outfit; the rich blue colour and gold, floral design is what makes this ensemble evening-wear worthy.
Rihanna picked up that gold element with her choice of jewelery and the fact that her hair is not blonde anymore makes me happy.
