A good source of data to build an algorithm for bra fitting, is women tailors in India. Specifically, I would ask and observe how they fit women for cholis (sari blouses). The fit of a choli is similar to a bra, although the silk or cotton choli fabric is usually less elastic.

This November I got my first cholis; it took two fittings for an expert tailor to make them fit correctly to my form factor.
