There seems to be some controversy about whether or not fashion films (a short film created to convey the feeling and inspiration behind a designer's line) are beneficial to designers or not. Some may argue they are grainy and don't show the clothes very well, but I think it's pretty obvious that if you like the film, you will adore the fashion line. I am a big fan of these shorts and watch them incessantly. They are usually ethereal, unabashedly girly, and exactly tuned to my esthetic. Here are a few recent favorites:
The Harvest by Lover. Dreamy gold-tinged film inspired by Terrence Malick's Days of Heaven.
Samantha Pleet 2010. Adorable road trip adventure with a cute blonde and scene-stealing brunette.
Opening Ceremony's Non Plus One Final. Almost too twee for words, this short stars Jason Schwartzman and Kirsten Dunst being adorable and falling in lurve. I would hate it if I didn't adore it so much!
