I had some real trouble with all the bras I had before when I was in pain after surgery and I went to Victoria's Secret and explained to the nice lady there and asked for help.
She was so nice and the bra she suggested was perfect for me. The brand is IPEX and I got a nice wireless one that is so comfortable I can even wear it while sleeping when the breast pain gets to me.
I highly recommend this bra.
I wish you all the best.
