Tonight at 9/8c on OWN, Rihanna sits down with Oprah for what is sure to be a tear-filled interview about music, her road to fame and, of course, her feelings on ex Chris Brown. A much lighter subject that we hope Oprah touches on? Rihanna's sartorial evolution, in which she's transitioned from sweetly sexy crop tops to glamorous evening gowns to trendsetting avante garde streetwear in the time some people go between haircuts. Above, a look back at Rihanna's style over the years. And don't miss "Oprah Next Chapter" tonight at 9/8c on OWN!
