Halloween Party on Saturday

For the third year now my sister Jemma is having a Halloween Party, its always on the Saturday before Halloween. This is also doubling up as a leaving do for her and the family, so it will be a good one.
Costumes and cocktails are essential ingredients at her party, if your not wearing one your not coming in. I will be wearing a blood stained lab coat yet again, not sure what to wear underneath, maybe nothing?I am also in charge of the cocktails once again, frog spunk anyone? Will post some recipes when i get a chance.
Here is a selection of photo's from last years bash, that is not me in that lab coat it twas a foul impostor! (Even on Halloween i don't quite look that scary).

The skeleton on the bog is Stella not actually a child who drank too much. The children where safely locked in a room away from drunken adults.

Hopefully there wont be as much mess to clean up this year as most things have been packed away for the move, from the kids toys to the office furniture.
