Out of all the amazing songs by One Direction, I would say that Little Things is my favorite. This song is the boys' own way of telling girls that they're all perfect just the way they are. It basically says that all the flaws a girl has makes her beautiful and she shouldn't try to change herself. You don't have to try and be perfect, because those little things make the perfect YOU. Just like the lyrics say: "It's you they add up to."
