Jeff I do not think you understand my answer.
I do not mean at all that it should be used as a form of chastity belt. Instead, I point out the problem that the metal will destroy the silicone. If you have hold in a a real metal chastity belt, you understand that it is not completely smooth and soft. Many places as D-rings, second shield, lock, where there is a risk of destroying both fabric and high quality silicone.
This silicone bra "skin" has a flat inside and I think it is more a thing for transgenders. Not girls and women with real breasts.
