Style Showdown: Rihanna & Kelly Rowland

Here is another edition of "Style Showdown" featuring KELLY ROWLAND and RIHANNA in a Simon & Bide dress. This is a different design, and I like it. Rihanna wore it to a Bone Marrow Benefit, and Kelly Rowland wore it in a photo shoot. They both look fierce, but what do you think. I personally like it on Kels.
