This is an advert for Amphirite: Underwater Goddess, a perfume by Damien Krisl. I really like the feeling of this clip. Perfume commercials are always very 'arty' and 'vague', which sometimes works, and sometimes doesn't. In my opinion, this one does definitely work.
It's the movement of her dress, the comparisons between her and some underwater animals, the colors and the lighting which give me a nice feeling.
Now let's hope the perfume also smells great!
