Costumes.

We decided that we would have to have a fairly normal costume because we are only going camping in the beginning so things that would keep us warm are essential.
Here was my costume:

I choose the warm jumper because it would keep me warm, and the trousers are slightly farmer-ish, and the boots will help when its muddy.

Other group members did the same as me, the wrapped up in hooded jumpers, large coats, wellys and many other things.

We understands the importance of costumes because is a Zombie/Monster thriller all the clothes would be ripped and blood on them, if we did this, it would look silly.
