Doesn't matter. If she was hit in the back the arrow would pierce through and we could see it. Instead, we can see that something went all the way through because she's wounded in the front.
It would take a ridiculous amount of speed for someone to shoot an arrow through the human body. Bullets sometimes don't go through all the way - and they are shot at a much, much faster rate.
