I would look at doing a tattoo... you won't risk it falling off, not taking, looking funky... just something else to look into. I haven't had mine nipple added back on yet, but I'm looking into doing the tattoo's. There is some tattoo artist listed in the form for providers - check it out.
Also a great story about how tattoo nipple art is becoming more of the go to: http://thedailydebut.com/?p=1670

I had my dr put on nipples, and she did an awesome job. They look real.

My surgeon did the nipple and areola with skin grafting from my inner thigh.

I have reconstructed nipples and decided not. to have tattooing done. My reasoning is when I go braless I don't have to worry about the brown showing through my shirt

I actually have my own nipples, but they are quite numb. My sisters had the tattooing done, but in time, totally faded and everything was the exact same color/complexion. They were advised they could have them re-tattooed, but opted against it. I call them Barbie Doll boobs....LOL
