I have lost 13 lbs so far and I did shrink in my chest (thank GOD!!!) but I can't remember how much exactly. 1" for sure, possibly 2" (I have the measurements at home). I measure myself across the boobs, not under bust. Despite the shrinkage, I still wear the same bra size (and no need to get a smaller one). I think I would gladly make a donation to church if I shrank from a D to a C cup (in spite of being an atheist).

Oh tomato you made me laugh!! Thanks I'm quiet sure mine are shrinking it's just the way they look will do measurements in a few weeks :)

I have definately lost in the chest. From 42DD to 34C. Hopefully they'll hold right there.;) Of all of the times I've lost weight it's never been very significant in this area...so who knows??? The body definately has a mind of it's own!
