M.D.
I never found one that was good for both hand-free pumping AND nursing. The circles that are cut out in the hands-free bras are not wide enough for the baby to get a good latch. Because if they are any wider, they won't keep the pump in place solidly enough to be hands-free. So I'm not sure that this combination can work.
For hands-free pumping, I found a pumping bustier online that worked great for me. For nursing, I liked the nursing tank tops that you can buy at Target - great for discreet nursing in public, because when you pull your shirt up to get to the clip, they cover your belly and keep covering your belly even when you have baby latched on with a light layette blanket over your shoulder. And even just around the house, in the winter, it kept my belly covered and warm.
When I pumped one side and nursed the other, I always held the baby with one hand in a football hold, and so I had the other hand available to handle the pump. Also, FWIW, the electric pump was too distracting for the baby anyway. So if I was going to pump while nursing, I used a hand pump.
