Ok, so my sister has quite a circle round type face, and she wants to cut her hair to make it suit her face to make it look not as round. There is a website called: http://www.taaz.com/

And what you can do is upload your own photo (make sure your hair is out of your face) and put things such as mascara, foundation, eyeshadow etc. on your photo. You can also look at hair. Every type! Curly, straight, long, spiky etc. The hair that best suits a round face is a bob cut with a kind of side fringe around one eye. It looks really good about a bit uner the chin.
Try going to the link below but anyway I think if you have a round face you could pull of short hair it's all about factoring in bangs, layers, etc. It could turn out really good.
look up a guide to see what face shape you have i have a square face shape and round is more like you have a half circle for your jaw.

answer mine?

well..... if u don't notice that yur jawline is angular that probably means yur not square, and round would be that your yur chin doesnt seem that pointy compared to your whole jaw... ^^
