I sported short hair last year (shoulder-length, to me that's short since i could NEVER go any shorter than that ) and I JUST got it to the long length I always wanted, so i'm not cutting it any time soon!!
I had pretty long hair (below the bra strap) but it was in bad condition and I cut it just above my shoulders. BAD MOVE. It makes my face look twice as wide and gives me a serious man-jaw. Not to mention I now look like I was severely beaten with the ugly stick
It's amazing the difference hair makes to the way you look - I haven't been able to wear my hair anyway except tied back for the last 3 months and probably not for the next year at least
