What butch haircuts would look good on me? Pictures included?

Why not Winona's style? In that picture or otherwise. If you really look like her, you can pull that off, and make it a little more shaggy for some edge rather than femininity. By the way, I am completely jealous of you and admire your decision to go with a bold, short haircut. I'd kill to be able to pull that off, but it just would NOT work for me. If I could and still be comfortable with it, I'd buzz my hair in an instant! But nah. Good luck!
