Barbie and Ken question?

My boyfriend and I want to be Barbie and Ken for Halloween. I'm planing on using something like this: http://www.polyvore.com/cgi/set?id=11456 … But I do not know what to wear. I was thinking maybe I should wear jeans, a leather jacket, a shirt like this http://www.hollisterco.com/webapp/wcs/st … and maybe sunglasses and hair gel or something. I worry that people will not be able to tell what dressed however. = / Or be able to say he's ken = / Any ideas? Thanks in advance! =]

Preppy clothing. That was Ken's. A doll of preparation. So maybe khakis and a shirt Aeropostal (the center of all preppiness bothersome) and a sweater tied around his neck …. I have no idea ..
