I've seen different sets of people from around the country mention a "custom party" on written Halloween invitations. Does it simply mean costume (and just intentionally mis-spelled)? Or some specific kind of costume?

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, see the FAQ.
As you will have gathered from comments- the writer of the invitation cannot spell, and means 'costume party'
You can use custom to mean bespoke, but you would need context for it to mean anything here.
