Hello! I have also undergone a mastectomy on the right side and have had a hard time finding a comfortable bra. The most comfortable I can find is a very soft sports bra made by Hanes. Believe it or not, I got it at Walmart for about $9.00. It's reversible, so there are no harsh seams. It's made of soft T-shirt like material and is stretchy. I am undergoing breast reconstruction so I look for good support of the new breast as well as softness against my skin. Good luck and God bless you. We are survivors!
