In Sex And The City 2, actress Kim Cattrall wears Roberto Cavalli Corniola sunglasses. Her character Samantha Jones is wearing these sunglasses while lounging at the hotel pool in Abu Dhabi. The glasses seem to have a white stone near the hinge, but dark arms and brown gradient lenses. The stone might have been changed for the movie, because this exact color combination doesn't seem to be available. These Corniola sunglasses come in several color combinations.

In the same movie, Kim Cattrall also wears Jee Vice Red Hot sunglasses and a pair of Theo Commodore in the camel ride scene.
