I actually found this by clicking on a banner ad; it's a series of short films and interviews for ModCloth and many involve wetlook; one involves a small amount of mud. The aesthetic in the filmmaking is really beautiful!
(Friendly reminder to respect the nature of the project and keep any YouTube comments limited to the aesthetics of the filmmaking, not demands for the models to re-film it wearing white socks and wristwatches and...actually, I think the model who submerges in the rain puddle is already wearing white socks and sneakers.)
