CMA Fashion Face-Off: Miley Cyrus vs. Taylor Swift

They may be BFFs away from the red carpet, but they're pitted against each other in this Fashion Face-Off.

Miley Cyrus and Taylor Swift wore similar dresses to last night's Academy of Country Music Awards. Each wanted to show off the sex appeal of just one shoulder.

Swift actually beat out George Strait, Jamey Johnson, Montgomery Gentry and Carrie Underwood for Album of the Year at the ceremony. Will that momentum carry over into this battle?
