I got it from Amazon.  I am really comfortable in it. I forget I have it on. I have been wearing it every day all day.  It conceals my breasts well.  It invisible under even tight-fitting t-shirts.   
It is advertised as men's compression corest.  I have bought many compression shirts and they all are way too tight and uncomfortable. I feels like I can't breathe in them. But this one is different. It fits and looks like a bra, but does flatten my chest out enough to not look quite so breast like.  Which is exactly what I needed.   I have a drawer full of t-shirts I am wearing again.
