Last night Rihanna was named the Queen of West Hollywood’s Halloween Parade and received the key to the city. Afterwards she hit the red carpet at Greystone Manor where she hosted her own costume ball. Rihanna wore The Row‘s black sleeveless ribbed dartford top and a lace panel skirt from Dolce & Gabbana‘s Fall/Winter 2012 collection. She finished the look with Azzedine Alaïa‘s mesh ankle boots. Her jewellery included a diamond bracelet/ring combo by Sue Gragg. Rihanna was styled by Nini Nguyen.
