Apparently, the model was misled about the purpose of the photoshoot. According to Rox, she was told that it was for a movie about Japanese fashion. http://woxje.tumblr.com/post/17484416773
Even aside from the subject matter, it looks very amateur and poorly made. The trailer makes the movie look SO BAD. It shows 2 second-long clips from interviews that make it look like experts are saying that pedophilia is acceptable. Looks like a classic case of interviews being taken way out of context.
From the trailer, I get the feeling that the movie is trying to say it's natural for adult men to be attracted to teenage girls. Honestly, I do think it's natural to be attracted to youth. However, in a modern society, it's not ok to pursue teenagers for marriage and especially not for casual sex. I think most people agree with this but some dumb wannabe film maker decided to sensationalize this natural attraction to youth.
The image of a beautiful girl in a beautiful Angelic Pretty dress is very striking which is probably why it's being used to promote the movie. However, it's misrepresenting the fashion, which is totally unrelated to pedophilia. Maybe the people who made this movie googled "lolita" and found Angelic Pretty that way.
Using lolita fashion to promote a movie about pedophilia is so stupid and irrelevant because...drum roll...most guys are turned off by lolita fashion!! If men were attracted to lolita, then all the sad, single, boyfriend-hungry ladies out there would wear lolita. Lolita fashion gets comments like, "You lost your sheep!" Low-cut tops and push-up bras get real attention from men!
The lolita community is pretty annoyed about the poster. I am too!
