Ines it's impossible unless it becomes a trend, and in this case, it will be an item of fashion, but probably without the lock. In the past, sometimes fashion borrowed from bondage world, but fashion items did have not the closing or restraining elements. They are just for show, not the real items. The real one (for example, a collar locked with a padlock) will not be acceptable in a lot of environments. Same for chastity belts. If created just for fashion maybe, but the real thing will surely be looked at badly. It will be very divisive, a lot of arguments will kick on, and the purpose will disturb a lot of people. Even if you remove the parenting part, in the collective imagination a belt is the flagship of patriarchy. I can't even imagine an item that speaks more about patriarchy than a chastity belt.
