Cameron Diaz
At the premiere of What To Expect When You're Expecting in 2012.
Sarah Jessica Parker
The star brought in mixed reviews when she wore this Couture piece to the Costume Institute Gala last summer. The actress, who was escorted by the designer, accessorized the silk taffeta floral print gown with Fred Leighton cuff bracelets, which she wore over the sleeves.
Keira Knightley
The actress kept accessories and styling minimal at the Los Angeles Film Festival, where she promoted her flick, Seeking a Friend for the End of the World. This tulle gown featured floral and silver embroidery and was a statement on its own.
Anne Hathaway
The star celebrated the designer in a long-sleeve floral dress at the New York City Ballet Fall Gala last September. Days later, she was married in a custom Valentino gown.
Diane Kruger
This fashion icon kept it classy at the Toronto Film Festival, wearing a long-sleeved dress with a short slit and a high bun. She chose a simple Manolo Blahnik pump to go with the frock from the label's fall 2012 couture collection.
Rooney Mara
This classic Valentino red is a far, but pleasant, cry from the black we are used to seeing the actress wear. She shortened the sleeves on this gown from Valentino's spring 2012 collection and paired it with a smoky eye.
