Rihanna and her band hit up Grammy rehearsals yesterday evening. They had a successful performance the night before at the 2016 MusiCares Person of the Year event. A picture from yesterday’s rehearsals has popped up and we got to see a bit of Rihanna’s outfit. At last year’s rehearsals she sported a mix of Jean Paul Gaultier couture and Craig Green menswear. This year, however, she rocked a dress from Nina Ricci‘s Fall/Winter 2015 collection [Look 21].sold out.
