The Cannes Film Festival officially began this week, and so far, the only I've been able to focus on is figuring out what products Gillian Anderson uses on her fluffy curls. Anderson is currently in France, where she's joining the rest of her castmates to promote their upcoming horror movie, Teenage Sex And Death At Camp Miasma . On day two of the festival, the actress stepped out wearing a nude Miu Miu midi dress with silver and beige floral embroidery that she paired with strappy burgundy heels. Her glam for the day was even more summery than her dress. Anderson wore a light pink lip color along with a hint of blush and dark eyeliner. On most occasions, she wears her creamy blonde hair in straight styles and updos, but for Cannes, she opted for big, springy curls that were slightly teased to add some extra volume.
