Last summer I had a discussion about this with Chele Marmet.  If I remember
correctly, she had said tubular looking breasts are often judged as
insufficient glandular tissue.  She said the key physical appearance is wide
set breasts that are markedly different in size.  The breasts are wide set
because most of the breast tissue is in the distal portions towards the arm
and very little is in the medial portion.  Her book, LACTATION FORMS, has a
picture.  In addition, the book states, the breasts do not grow during
pregnancy nor does the mother experience engorgement post partum.
