They are two of the most beloved, gifted young stars alive - and they might get along very well in real life.
But this is the virtual world, Kristen Stewart and Taylor Swift, and there are no friends in the world of fashion face-offs!
The actress and the singer each wore the same J. Mendel dress out to public events over the last few months, although Stewart chose the strapless ivory version, while Taylor rocked it in lavender.
This photo of Kristen is also outdated because she's cut and dyed her hair since she walked the red carpet for the premiere of New Moon, but that doesn't mean she can't still take on Swift below. Compare, contrast and vote...
Who wears this dress best?
