Fashion Face-Off: Rihanna vs. Rihanna

Rihanna makes almost as many headlines with her fashion as she does with her music. Okay, maybe that's a stretch, but her style is pretty noteworthy!
Never one to shy away from bold colors, the star goes went for a vibrant look - right down to the turquoise shoes! - as she left New York's MTV studios.
Then, she was blooming again in a longer, floral dress at the signing of her new coffee table book (called Rihanna) at a Barnes & Noble. Which is better?
