It's a battle of the sexy Oscars dress with a thigh-high slit!

Both Taylor Swift and Andreja Pejic both wore the same Alexandre Vauthier Couture dress on Sunday while celebrating the Oscars 2016!

Taylor worked the red carpet at the 2016 Vanity Fair Oscar Party in the sexy dress while Andreja struck a pose in the same dress while attending Elton John's annual AIDS Foundation Academy Award Party.

While both Taylor and Andreja rocked the exact same dress, they styled it a little bit differently. Taylor chose to have the neckline plunge all the way down to her belly button, while Andreja kept it a little more conservative at the top.

They duo also paired the look with totally different shoes!

So while both Taylor and Andreja looked stunning, which star do you think wore the dress the best? Vote now in our poll below!
