Rihanna vs. Caroline Sieber

Rihanna debuted the look first on the cover of April's Vogue, pairing the dress with fiery red hair  and matching lips. It was a tough act to follow, but Sieber took on the challenge four months later at the Chanel Haute Couture Fall/Winter 2011/2012 show at Paris Fashion Week. Going for a more subdued look, Sieber wore minimal makeup and let her shiny brown tresses hang loosely around her shoulders.
