I have no idea what a pixie cut is but my wife cut her hair short about 50 years ago and she wouldn’t have long hair again if you paid her.
Strangely enough, I am one of those rare birds who looks LESS feminine with long hair. There's a picture of me with longer hair when my girls were very young ( they don't remember a time when I didn't have short hair.) We were looking at old pictures one day and one of my daughters shrieked, "Who is THAT"? She thought it was positively scary and I agreed.
I finally found a stylist who gives a mad pixie cut with a straight razor. He's worth his weight in gold, and I am frequently complimented by both men and women on my appearance, especially since I stopped coloring my hair and now have a very nice silver crop that is darker along the bottom edge. I've been told that it looks like I spend a lot of money to achieve my look. Only my hairdresser (and now FR) knows for sure!
