Nicole Kidman Tops The Best-Dressed List This Week In Stunning Dior (PHOTOS)

This week's best-dressed celebrities experimented with lots of texture and detail. Case in point: Sienna Miller, whose lace cocktail dress proved that she is back on the style scene in a major way.

Strapless necklines are definitely having a moment, too. Nicole Kidman stunned at Cannes in a strapless gown that looked like it had just come off the couture runways. We also saw stars pairing white dresses with deep red lips. Carey Mulligan attended the premiere of "The Great Gatsby" in Cannes in a white gown that was reminiscent of Gwyneth Paltrow's famous Oscars gown, but then added contrast with bold lipstick. Model Amber Valetta followed suit in a white cocktail dress, and kept her look interesting thanks to a burgundy pout and fabulous accessories.
