Diane Kruger has shown nothing but showstopping glamour during this year's Cannes Film Festival, so it was only appropriate that she go out on a high note. The actress and film festival juror attended Sunday's closing ceremony and the premiere of Thérèse Desqueyroux in a wildly voluminous Christian Dior Haute Couture ball gown. The black, white, and gray plaid confection had a structured bodice and was accompanied by a very Victorian-inspired bustle and train. She kept all eyes on the gorgeous gown by keeping her hair and makeup slightly subdued and accessorizing only with a pair of diamond earrings.
