Umm, I'm not exactly sure what makes a face "the right face" but from what I've seen, if you have high cheekbones and a slim face you can pull it off. Girls that have rounder faces tend to look chubbier with short hair. It's hard to say whether you'd look good with short hair without seeing what you look like.

If you have a really round circle shaped face, don't do it. It'll make your face look fat. If you have an oval face with a more pronounced chin, then you should be safe.
