Naomi Watts In Marchesa - ‘How To Train Your Dragon 2′ Cannes Film Festival Premiere

Naomi Watts attended the ‘How To Train Your Dragon 2′ premiere during the 67th Annual Cannes Film Festival this evening (May 16) in Cannes, France.

There are very few traditions left when it comes to Cannes, but you can always rely on Naomi to wear Marchesa.

Naomi wore an exquisite, graceful custom dusty blue silk chiffon draped Grecian gown with black diamond crystal embroidery, with a cowl overlay sweeping through the sweetheart neckline.

As the face of Bulgari, she donned a diamond-encrusted serpent necklace that snaked around the back. On an ordinary night this may have been considered overkill because of the embellishments on the gown, but this is no ordinary night.
