I bought these before I had my shoulder surgery because I read up and found out how difficult and how long it would be before I would be able to reach around my back to put on my bras again.  These bras were wonderful!  Actually took one with me to surgery day along with the t-shirt I retrofitted with velcro on the shoulder so I could slip it up my legs (instead of over my head) and secure it at the shoulder area with the velcro.  My mother-in-law also borrowed these when she had breast surgery so she wouldn't have to reach around to secure her bra after surgery.
