Any ideas for a cheep nativity outfit for my 20 month old?

[Taichimum]

I need to dress my ds up in some sort of nativity outfit. Anyone got one to sell/give away or any ideas of creating one cheaply?
Already thought of tea towel on head and dress gown idea but no way ds will keep the tea towel on.

surely there's no way he'll keep anything on?

when dd was that age I dressed her as a shepherd by cutting a hole in a bit of brown felt to make a tabbard, tying it up with a bit of string and giving her a toy sheep to hold. it turned out that the spanish have a completely different idea of what shepherds wore in 1st century palestine, but that's another story.
