I can’t help a lot sorry but have you got the little pillow that goes over your shoulder and protects the scar from weight of your arm esp when sleeping ? Also I was uncomfortable after surgery with my Target post op bra for months and swirtched to an aah bra and the difference has been amazing - so comfortable no seams.They are odd in that you step into them and pull them up , and not particularly attractive .Variations on this product are available Target , Best and Less , KMart -I bought mine online - they are cheap too.I think some stores call them sports bras.
