For a perfume ad of course. It's funny how that the Calvin Klein commercial with Eva Mendes rolling around in bedsheets gets banned in the U.S. while over in Europe, no one bats an eye over this Guerlain perfume commercial.
Natalia goes completely nude (you even see side boob!) and caresses herself with her hands and the perfume bottle. A little corny but effective. Hey, I'd buy it.
