Who: Mia Wasikowska.

When: Tuesday, May 10.

Where: The European premiere of Alice Through the Looking Glass.

What: A chiffon gown by Prada with green and black sequins and black pumps, also by Prada.

Why: Wasikowska's trademark fresh-faced look places her decadent gown front and center. No accessories, minimal makeup, sleek hair, and a trailing, sequined dress make for the ultimate red carpet look, and a suitable concession prize, while everyone else is away at Cannes.
