My wife uses sports bras that she buys at Kohl's I think, some kind of synthetic with no wires or padding. That's all I know about it, but at least it's a place to start.
I don't exactly have man-boobs at 155 pounds, but when I started jogging I was recovering from a collarbone and it was somewhat painful. I used a tight compression shirt - I think some weight lifters like those - and it helped immensely.
