When I think about this type of project, the first that comes to mind is perfume commercials. Which ones are your favourite? One of my favourites is a piece directed by Guy Ritchie for Dior Homme, starring Jude Law and Michaela Kocianova.
Another great example is this Prada commercial starring Daria Werbowy.
There are other promotional projects of a more general and experimental nature, like this short film directed by Karl Lagerfeld, starring a team of Karl's favourite models. This one was received with mixed reviews.
