Rihanna has many looks and styles, but I must say this is one of her best looks. The Bajan singer hit the Queen of the West Hollywood Halloween Carnaval Ceremony looking very sexy wearing a black Dolce & Gabbana skirt, black scoop-neck top by The Row, and paired her look with black Alaia Booties. We also love her new hair color — very attractive and seductive. Check out more pics of her on the red carpet!
