Well then, I reckon I'd have to do Lucy's funny voice too. That will be such fun! I'll bet we could find some good stuff at a charity shop, cheap too.
I think I would dress as an Ood if I had the time and tools to make it happen. They're a lovely race. Not exactly lovely looking but let's be honest. Not all humans are lovely looking either.
I think Lucy would be easy and still look well put together.
