I have thought that the ideal of sexual dimorphism excededs the reality of it. I once tried demonstrating that here by editing a picture of George W Bush by changing only his dress and hair and yet he made a pretty convincing woman. I think people may take their cues from hair and clothing more than they realize. Remember the faux dude in the movie Liquid Sky? This lady here shall be soon deleted by a moderator I suppose unless we can get lisensing from the estate of the photographer.
