What haircut should I get?

I have long hair I don't really know where I'm going with it right now so I usually just stick it in a pony tail, I want a haircut that will flatter my face, but i don't have to style it a lot every day to make it look presentable. My hair is wavy and brown (if that makes a difference) I have a square face and my cheeks are kind of chubby. Someone find me a hair cut that will elongate my face? Not above the shoulders please :)
