Unless there is some serious miracle bra and "chicken cutlet" action going on or the smaller ones are from an earlier time frame it is hard to believe those are even all the same woman.
So the photos are "before and after" and the photos of her that actually show her boobs are "before" ?The left one certainly does NOT look smaller than the right one anymore.
Much smaller, is it now or are those pics older...maybe she got upgrades.
