Fashion Face-Off: Carrie Underwood vs. Khloe Kardashian

Carrie Underwood has already taken on Kim Kardashian in a fashion face-off.

Now, the gorgeous singer is setting her sights on Kim's little sister Khloe.

Underwood donned this purple Badgley Mischka dress for the 2008 Country Music Telvision Awards, while the reality star attended a fashion show in the black version of it last month.

Two wholly opposite celebrities. One outfit. Who wears it better?
