Okay, I just bought this today:
http://www.herroom.com/fine-lines-ss...-bustier.shtml
It goes up to a 40G
It is fine lines bustier, style: ssp025
Hopefully, it will help with both my posture and also the problem of bra straps pressing into my shoulders. Also, I'm fearful of putting anything over my shoulder while recovering from surgery.
I tried a few different styles on, and this one seemed to give support up top, but also be loose enough on my belly that it wouldn't hurt sitting down at work all day. Hopefully....
So glad I have a daughter and not a son!
