Kristen Bell was serving it up this week at the Frozen 2 world premiere. She sported this gorgeous burgundy Dior gown with a keyhole cutout. She accessorized her sexy ensemble with very simple jewelry, just some diamond hoops and matching bracelets. And she kept her makeup very soft and natural, with a pop of pink on both her eyes and lips. And her hair? Just a simple, unfinished bob. Perfect for a princess. How do you feel about Kristen’s look?
