Kate Mara attended the 2015 Will Rogers Pioneer of the Year Dinner held at Caesars Palace on Wednesday in Las Vegas.
She is currently promoting her upcoming superhero film Fantastic Four at CinemaCon, the official convention of the National Association of Theater Owners.

The 32-year-old American actress donned an unflattering off-white dress from the Valentino Fall 2015 collection.
Kate styled the lace mini dress with Jennifer Meyer jewelry and a pair of ankle-strap sandals from Jimmy Choo.
