Most Helpful Guy
It's really hard to say. Some girls look great with a pixie cut, others look awful, and I can't ever put my finger on what it is that makes it so.
First pic: looks bad (though that lipstick isn't helping)
Second pic: looks really cute
Third pic: looks pretty good
Case in point: Emma Watson. Even a girl as good looking as she is couldn't do a pixie cut well.1
