It was a night of daring fashion at the Billboard Music Awards on Sunday, which means that there were some big hits -- and some major style misses. Billboard's 2011 Woman Of The Year Taylor Swift looked elegant as always in a sweeping floor-length red gown, and ever head in the crowd turned when Miley Cyrus walked down the red carpet in an oversized, low-cut white blazer, creating a daring look that gave rise to mixed reactions.
Top Social Artist winner Justin Bieber rocked his signature look (big sneakers, jeans, jacket and hoodie), while his friend Carly Rae Jepsen ditched her usual playful style for a more mature nude-colored gown. But it was Katy Perry who stole the spotlight with the best accessory of the night: her adorable grandmother!
