Imagine you are at a party that is themed on the 1980's. Someone walks in and says:
"You realize its not really the 1980's right" ? 
I'm the kind of person that if I got an invite for a party and to dress for a 1980's Theme, I'd show up and be the only one dressed for an 1890's Theme....
That's a pretty big IF though. I don't get invites to parties.
