Dressing up as your characters means you can put on a whole different persona, and behave entirely outrageously - because that's your job. I first realised this when I put on a pirate suit and became my alter ego, Lucy, Pirate Queen of the Seven Salty Seas (it's amazing what a bit of lace and a ribbon on a hat will do to me, let alone a full double-breasted red frock coat). I find it gives me the courage to talk in a ridiculous accent, play the tambourine and even sing. I regularly get asked where I've tied up my ship - and where I've hidden my treasure, especially when I'm travelling to an event by bus.
I hope I don't regret it. No doubt there will be pictures. I may even come back and post some here. Be afraid.
