What is the best short hair cut to get for someone with an oval face?

I'm currently 23yrs old, as my hair is getting pretty long and I feel it makes me look younger than i am. Therefore, I want to get a shorter hair cut to make me look older/mature. Does anyone have any hair cut suggestions for me, as I have an oval shaped face and the only thing I'm nervous about getting with short hair is that it will make my face look chubby, which I dont want to happen, as I had that happen before. So if i could get some ideas, that'd be greatly appreciated. Thank you so much.What is the best short hair cut to get for someone with an oval face?

I have a very oval face and when I got my hair cut I went with the Sophia bush, one tree hill most recent season cut. Its sleek sophisticated and I can put it in a ponytail

look at cwtv.com and click on photos of onetreehill # 75-#79 are really good pics of her hair straigthened
