Mike_Orca lockable but more comfortable garment that serves the same purpose? A kind of chastity shirt with solid plastic cups and a lockable zipper, e.g.?
Interesting concept, but rather unrealistic. How do you imagine such a structure? The bra has basically only two dimensions - the circumference of the chest and the size of the cup (+ the possible length of the chains on the shoulders and connecting the bra with the belt). The shirt has much more of them (chest width, total length, collar circumference, length and width of the sleeves), which makes it much more difficult to match something like this. The chastity bra, due to its function, must be tight. Thanks to this, it can be worn secretly under clothes. The shirt would also have to be so tight, I suspect, which would make it even more uncomfortable than a bra. On the other hand, a loose shirt would not fulfill its function, because the cups would protrude from the breasts. As for the locked clothes, of course, they can replace the chastity belt and bra, but only in the home environment. It is enough to wear boxing breast and crotch protectors under the tight locked overall.
