Mia Wasikowska in J. Mendel | “Lawless” Premiere – 2012 Cannes Film Festival

Mia Wasikowska joined her large assembled cast of “Lawless” tonight for the 65th Annual Cannes Film Festival premiere of their crime-drama film at Palais des Festivals.

The 22-year-old actress looked beautiful in a Fall 2012 plum textured silk cloqué deep v-neck gown by J. Mendel.

I usually have such a on-and-off relationship with Mia’s wardrobe — it’s usually off — but, thankfully, it was totally on for her first red carpet appearance at Cannes this year.

The rich color of Mia’s gown was stunning and she wore it well.

She kept her accessories light, so the main focus — other than the dress — was her hair! Mia wore her bob-length, dark blonde tresses in a braid that started from her forehead and traveled straight into an elegant chignon.

Mia finished off her look with dark open toe heels and a small pair of diamond earrings that matched her tennis bracelet.
