I've been invited to a Halloween party. The first time I went to this party I wore a nightie, dressing gown and slippers, with a teddy in one pocket and a hot water bottle in the other pocket, and said I was having an early night. This went down very well, but I don't want to repeat it. Everyone else at the party had put a lot of effort (or money) into their costume.
I need inspiration. Something as comfortable and as funny as my "I'm having an early night".
Any ideas?
