Evangeline Lilly is playing an all-new character in the second movie in Peter Jackson's Hobbit trilogy, The Desolation of Smaug, an elf named Tauriel. All we knew about her character is that she has some kind of relationship with Legolas (who will be stopping by the film) but now we also know that she may have borrored her outfit from a high school production of Peter Pan.
So much wrong here, I'm not even too upset with the costume design/colors but if you're going to have someone in a movie that I'm assuming will be using a weapon at some point you should at least teach them how to use it.
The arrow should be resting on the other side of the bow and the fletching should be up by her cheek, there's also the problem with her quiver placement snagging the string every time she shoots.
