A good point Expat,

You are correct that being in prison/jail is the punishment. But once in prison/jail there is no punishment other than for infractions inside. So seems being forced to wear pantz is an unearned punishment.

Understand the point about cost, but what about long term value. Would guess well made kilts could be reused longer that pantz would last.

Trying to image some prison movie remakes where the inmates are all kilted...Monty Python missed that one eh?
