Rihanna goes conservative for grand pa’s birthday party

This might just be Rihanna’s most conservative outfit yet, and with good reason. The singer has gone from talking about her raunchy Christmas wish list to celebrating her grandfather’s 86th birthday. Rihanna’s monochrome head-to-toe sweater is perfect for the occasion, as it is something any grandpa would call “sharp.” Happy birthday Grandpa Bravo!
