First, I think my pics on here are tasteful. I dress and have alot of cleavage because I liked my breasts.
Secondly they are so big, even a bigger shirt doesn't take away that.
Anyhow, I can kind of tell if a woman is deliberately showing off her cleavage vs her notdoing it.
I've seen photos of women who actually have a camer DIRECTED at their boobs in their bras (with their head cut off on top..not literally, lol)
But youc an get the image.
Or....the get a real deep lunching V Neck blouse...hold the camera "on high) facing downward...but you do see their face...
So they AIM it right at that spot on purpse.
