Epeirotes in Arpi - how to call them?

[MerlinusCDXX]

For added confusion, in Australia a "thong" is a sandal.

And to confuse things even more, here in the US, "thong" refers to both a sandal (of the "flip-flop" variety) and the "perizoma", though a "perizoma" is also called a "G-string" in American English. Confused yet?
