The idea behind the photoshoot was to echo the heavily natural aesthetic of the pastoral convention of literature (think Christopher Marlowe's "The Passionate Shepherd to His Love" and anything about shepherds and shepherdesses and their comparatively innocent lives in the countryside of England and Europe). Hence the natural makeup, mishmash of layers, and hippie-dippie hairstyle. I'm planning on writing more about the pastoral convention and how you can incorporate its aspects into lolita, mori girl, and a slew of other fashions, so keep an eye out!
