Hah! Had to log back in and comment because I love this stuff.
I have a long torso (like in one-piece bathing suits) BUT I am not long waisted. After much scrutinizing, I discovered where the extra inches are....between my chin and my chest! Or on this chart, the uppermost proportion, giving me not only a long neck but a large expanse of real estate at the upper chest. Even with a really good bra hiking the girls up as far as possible, I have a "low bossom" (and always did, even before I nursed two babies).
My sisters are built the same way, as we found out at our family reunion last weekend. I have never seen this issue addressed in any chart, but I have found bulky scarves work really well for me!
