Male wanting a feminized chest wall, is it possible?

I really don't want to get to into this, but ever since i was a younger kid i always had the desire to have a feminized chest wall like my sister did. I at one time i stole one of her bras and wore it and stuffed it to act like i had a feminized chest. I have tried taking herbal supplements to achieve this effect. I was able to get some growth but not much. I would like a permanent and guaranteed result. I am able to answer any questions you may have.
