Rihanna stepped out in a 90's iconic Calvin Klein slip dress last Tuesday. You may recognize it from 1995's teen hit Clueless, except Rihanna wore hers in red, while Alicia Silverstone's character wore it in white.  Calvin Klein reissued the style in 2010, just going to show that what's old is often eventually new again.
