I had a mast. with reconstruction and came home with no bra, no tube top, just drains. Button down is the way to go no matter what you are having done. Sometimes it's hard to raise your arm to pull something over your head. If you think you will have drains, pockets are nice too. Good luck and keep us posted.
Sending hugs and prayers your way.
Today is a gift, that's why they call it the present!
