Is that the difference between the rib cage measurement and the chest measurement ?

Hi nsas,

Actually it's measuring from the outside of the breast where it begins. Now measure over the fullest part of the breast (which means nipple to me) to where the breast would stop, and then over to the middle of the breast bone and stop.

If you don't have a clothing tape measure try string, just make sure your line is slack when measuring, and then measure on a ruler, if you pull it taught while laying it along side the ruler it will increase your measurement (giving you a bonus, lol)
