I've been invited to a moustache party. I don't think I'd ever heard of one these before, but it sounds like a good idea to me. Nobody I know has a real moustache (not without a beard, anyway), and the wearing of a flamboyant fake one might be a good way for shy people to hide their faces.
I might go for one of those moustaches on a stick that I can hold up like they used to hold masks over their eyes at balls. Seems like the sort of thing I could make myself. It has the advantage of being easily removable should I turn up and find that nobody else has bothered.
Moustache - it's a fun word to say as well.
