Lily James, Helen Mirren and More Rule This Week’s Celebrity Best Dressed List

Lily James is definitely having a princess moment. The breakout actress (and emerging style star) has been busy promoting Cinderella around the world and her gowns have fittingly embraced the movie’s fairy tale premise with embellished details and elaborate embroidery. When it came to color, blue and pink were the hot hues on the red carpet, thanks to Helen Mirren and Chrissy Teigen (seriously, what don’t they look good in?). Fancy footwear (think studs, extra straps, appliqués and bold prints) really upped the ante on several looks. We love the sheer variety this week with celebs opting for prim and proper dresses as well as more rock ‘n’ roll getups. Check out the latest crop of best dressed stars above.
