Fashion Face-Off: Rihanna vs. Rosario Dawson

As has been documented, Rihanna is quite the fashion maven and/or mess.

But the singer toned down her outlandish looks at the World Music Awards in Monaco in 2007, sporting a beautiful green Dolce & Gabbana gown.

Last week, Rosario Dawson followed suit; or dress, really, appearing at the SAG Awards in a champagne version of the same outfit.

Which star looks better?
