Stunning commercial for Y, by Yves Saint Laurent

Serendipity works in mysterious ways and often in reverse.
I found this amazing and rarely seen clip from at least two years ago, as part of a longer film about Tom Ford (?), for Y by Yves Saint Laurent, while searching for something else. It features model Elise Crombez (credit goes to cyrilguyot.com).
Please enjoy!
