no indeed, Sir Prior, those are unquestionably the Rolls-Royce of girl-shackles -
it's the compulsory cookie fast that's supremely sadistic!
They sure are, and am amazed on how well made they are.
Therefore I don't think they were made to be used for any lesser person who have committed any minor crime.
But as some sort of example for everyone else, saying see what will happen to you - and so a real deterrent to commit any crime.
So it have had to bee something that were quite offensive to one aristocrat victim, that without being really bad - like stealing the duchess jewels or something.
(This said as a hint if you find yourself in a time warp and don't want to spend your life toiling in the fields as a peasant.)
...and btw, no cookies for you, you'd bloat!
Saying that is indeed the reason I think the middle ring is so high, since it do not go around the waist, but around the chest - that in case the female prisoner do indeed develop a rounder belly over the year. There be no reason to remove these chains for that reason - now that the belly is not encircled but the chest where hardly anyone get any larger over the years.
Now that we're on the subject of chains and have seen some art - I can already hear the calls 'get on with it' so think it is time we have a look at the work of Yoshinaga.
He sure have made some imaginative contribution in the field of slave trade, unusual prison cells and whatsnot.
