Kate Bosworth was at Sundance to promote her film Black Rock at the Sundance Film Festival in Utah.

Kate looked really pretty in her red Antonio Berardi dress with matching red Casadei shoes. I actually like this look, but I do have one complaint. Spanx. Now, I konw that Kate is thin, but I have learned that Spanx (or something similar) keeps things smooth. And, I see a pooch.

The back of the dress had a deep in the back. I know that it's cold in Utah so I appreciate that she chose to wear some fashion as opposed to what Liv Tyler wore which you will see later.

Kate is the queen of barely-there make-up so I was happy to see her orangish red lips. It wasn't an exact match to the dress, but I liked the contrast. She also wore one of my favorite hairstyles which really helped to highlight the back of the dress.
