I like the idea, but adults usually get mad when kids come around in no costume but a mask. So if you are expecting to get some candy, try a different costume.
It's ok for Halloween but it's much better for bank robberies.
(My mob lawyer suggested I should remove that so I shot him, anyone know of a good lawyer? Has to be flexible, otherwise they can't fit in the body bags if things go south.)
Also not many people know this, but that mask is a HOLD item. When holding it you get twice the DDoS power than normal.
All the joking aside, unless your going to be wearing a slim-line black suit with a slim black tie then I wouldn't use it.
Or you could dress like the guy from the actual movie
Depends how popular each of them would be in the country you're from.
