zombie is a good one, if you get the makeup looking good all the girls can't resist examining it ... i found heheh
first, just shred an old white shirt a little, exposing as much skin as you feel comfortable with ... any trousers are ok
for hanging-off flesh i applied a little PVA glue to my face, waited until it was tacky and then rubbed some away ... painted face white, apply some greys and reds (face paint pencils) to edges of hanging-off-skin ... blood stains on the shirt if you're not feeling too subtle ... job done
just got to get the zombie walk down and you're sorted
plus when you're drunk the glazed over look fits right in
