No, Halloween was never that big here in germany. And so, I will not wear any kind of costume this year, like the last years too. I only dressed up once for Halloween in my childhood ... or better said, I wore a Jack O'Lantern mask. It was also the only Halloween I can remember where it was celebrated a little big bigger here. Maybe a reason is that we have, at least here in the rhineland, our own celebration with free candy and costumes (Carnival). But this is only a guess.
