My Dr had a binding. on with tubes draining the first week but after that I just wore a t- shirt and haven't had a bra on since. I was fitted with prothesis but probably never wear them

it depends on your particular procedure and your doctor's preference.

My hospital gave me a "BC Health Navigator" who was a nurse that followed my case start to finish. Sh provided as a "gift"(I am sure it is on the bill somewhere) the front zip camisole w pockets for drains. But it was excruciating. I wore only steri-strips and a button up shirt home....and for a couple weeks at least. Drains pinned into shirt. Now I have a couple cotton front hook sports bras that help me feel less vulnerable....but the reconstructed breasts are not as....bouncy as before so they are just for comfort. Very sexy....not.

I last wore a bra the day before my BMX (7/2013). I gues it depends if you are havinv reconstruction/expanders put in. I didn't znd my surgeon does not bandage or bind or in sny other way covers the incision prior to fischarge.
I came out of the OR with a light gauze bandage which he removed the following morning before discharge.

I had a compression bra on that the doctor provided when I woke up from surgery. I would ask.
