What is the best haircut for a 12-year-old girl with brown hair and an oval shaped face?

Well I am a 92 year old girl with an oval shaped face and brown poopy hair and I just got my hair cut and it was really long and I got it cut really short. About to my shoulders. Maybe a little shorter than that but anyway. It seemed that once I got my hair cut shorter that it took the length away from my chin and now my face looks really even. I enjoy it so much and it is so easy to handle. I recommend she get her hair cut to her shoulders. Take this advice from someone who knows what you are talking about!
