You gotta hand it to Jessica Chastain. Even when she’s posing for weird photo shoots in some creepy abandoned woods, she still knows how to pull off a dress.

Such was the case at the 2013 Giffoni Film Festival on Sunday, where the two-time Oscar-nominated beauty (why did she lose to Jennifer Lawrence? Why?) arrived in a red stunning dress by Dolce & Gabbana. The look was so flawless, we went ahead and named her the best dressed star of the week.

Who else looked good this week? Check out more from the ladies – plus a special appearance by a red-hot man – in the gallery, above.
