Perhaps sharing the new look I'm working on will give you some ideas. I'll go from head to toe (and by the way, all images were plucked from Google):
Hat:

or

>I figure the white will stand out very nicely.
Piercings
>I do not want to go all the way (at least not yet), so I will use fakes. Two on the top of the right ear, one on the lobe of the left.
Hair:

Although my look is a bit cleaner.
Facial Hair:
For now, clean - later, goatee?
Neck:
Feather Boa
>For lock-ins
Hands:
Have the fingers exposed - you know the look - on either on hand or both.
Torso - Outer:

(So cute!)
Bomber Jacket OR Vest
Torso - Inner:
Random, brightly colored shirt
Pants:
Jeans or pin-stripped
Shoes:
Chucks or nice-ish brown shoes?
I hope that gives you some food for thought. I'll take a pic when I've got everything assembled.
