Rihanna teams her plunging leather blazer with a sheer black dress as she joins her dapper boyfriend A$AP Rocky to celebrate her brother’s graduation at a swanky dinner in NYC

Rihanna showed off her elegant sense of style as she celebrated her brother’s graduation with a swanky dinner at the Mamo Italian restaurant in New York on Thursday.

Joined by her sharply-dressed boyfriend A$AP Rocky, the singer, 36, slipped into a plunging leather blazer and a matching sheer dress as they arrived arm-in-arm for the celebration.

Showing off her trim waist, Rihanna teamed the chic black blazer with the matching sheer black midi dress.

The dress boasted a sheer skirt and fun frilled velvet trim, and Rihanna completed her look with matching stiletto heels.

Rihanna accessorised her look with a black patterned leather handbag, and she brightened up the otherwise-dark ensemble with her vibrant blond hair.
