Will Decreased Breast Implant Projection Produce Significant Downsizing Results?

Breast Implant Size is a combination of subjective and objective
criteria.380 cc is a reasonable recommendation. There is not a direct
correlation between the cc's of a breast implant and the corresponding
cup size, as cup size is an inexact measurement that varies considerably
among companies and even within the same company. Online consultants
will not be able to guide you as well as surgeons who perform in person
consultation.The size of the implants are based on a combination
of a patient's goals and objectives and her anatomy. In order to
provide a natural looking augmentation, the surgeon needs to evaluate
many factors including soft tissue coverage, skin laxity, chest wall
width, breast imprint width, the shape of the breasts and relative level
of constriction to ensure that the breast implants are appropriate for
your body.

Based on the numbers, I think you will notice a significant decrease in breast size with the implants you have chosen.  Although there is very little science behind the "Cup Size", highly projecting implants have a significant effect on the appreciated cup size, so dropping 2 cm will make a noticeable difference.  The mentor implants should be significantly softer than your current implants.
