The fashion blogs went crazy when Rihanna stepped out in Pajamas for the world premiere of her new film Battleship. After investigating I found that this is indeed the Spring/Summer 2012 fashion trend. It was shown during fashion week by designers like Stella McCartney, Emillio Pucci, and Louis Vuitton. So ladies what do you say yay or nay? Whatever your verdict, sleepwear-inspired style is seriously hot right now.
