The ladies mixed it up on the red carpet at the American Music Awards last night, but most opted to show off their stems. Never one to blend in with the crowd, Beyonce decided to go with the mermaid look that was a favorite back at the Emmys. What did you think about all the red carpet looks and beauty? Rihanna usually kills it on the red carpet, but we all agree that she missed the mark this time around. Luckily she looked much better during her acceptance speech (click here for winners) and performance — more on that later. Overall, most of the ladies managed to look both glamorous and flirty but who do you think was the best dressed?
