Neither of the 3 options listed hun. Instead of Queen of Hearts, go as a slutty Queen of Spades chic with a gothic twist and your sure to get plenty of Black dick picking you up. Wear the shirt below with some black stockings and those black panties with the black body paint underneath the shirt. Make sure you take plenty of pictures and go trick or treating and knock on every BlackBull's door too. They are sure to give you some good hard Black liquorish candy for you all night.
We got an invitation a month or so ago to attend an adult Halloween party ... we kicked it around but never made the decision to go.
It's all about body paints and short skirts (no panties) for the ladies, though ...
My wife is a middle school teacher so I voted for dirty school girl but you will need to be creative because the girls from her school seem to have that look perfected, hope you have a great time at the party.
