AHH I am getting a hair cut tomorrow and need help!!!

I am getting a hair cut tomorrow and need some advice on what to do. I have a few pictures I kind of like but I don't know if they would look good on me. I am tall (6') and plus size so I need something flattering for that. What about Mary-Kate in this pic http://celebhairstyle.files.wordpress.com/2008/07/thin-hair.jpg or this one http://www.exposay.com/celebrity-photos/sandra-bullock-2006-mtv-movie-awards-arrivals-C3fIyL.jpg ? I also attached a pic of me
