I have a scar too, not very big. I just kind of play it by ear. If I feel someone is going to freak out about it, I warn them in advance. But if I don't sense it I don't say anything & they don't really notice it. When I bring it up afterwards, they usually say they would have never really noticed if I didn't say anything. Don't know where your's is but I can usually cover mine up w/ some kind of bustier. Good luck!
