Taylor Swift and Carrie Underwood are alike in so many ways: They're both beautiful blond country singers. But their fashion isn't always in harmony with one another. In honor of Taylor's "Speak Now" World Tour hitting stateside this summer, let's take a look at Tay-Tay's and Carrie's past fashion picks. Whose look hits the right notes with you?

Va-va-voom! Both Carrie and Taylor show off their sexy sides in red gowns with thigh-high slits. Taylor's strapless Monique Lhuillier wowed the crowd at the 2010 CMAs. Later that year, Carrie's red chiffon Edition by Georges Chakra dress was a success at the first-ever American Country Awards.
