Ok, here's my breast forms story. While crossdressing in private before I came out to my wife, I developed a method using newspaper bags (the narrow plastic sheaths that newspapers are commonly delivered in, in the US anyway). Vegetable bags from the supermarket also work.
Once you find a pair without holes

you can fill them with warm water, twist the opening a lot, double or triple fold the twisted part, and rubber band tightly. If you do it right they won't leak. The folded over part can be a "nipple" but it'll probably shift out of position

You have to wear a full coverage bra or they'll escape lol.
I still use them.
