I wear a mastectomy bra. No, I still have both of mine, but a friend said they were so comfortable. I can't get my arms back to fasten one, so these hook both front and back, I use the front hooks. They are the most comfortable I have ever worn. No riding up or straps slipping down. They stay put where I put them. If I have to wear one, this is it for me. Check them out at a pharmacy. My friend's husband is a pharmacist.
