What's the Maximum Breast Size You'd Recommend for Petite Frame?

 There is not universal size for breast implants.  It is best to individualize the implant size based on the individual person.  It is based on your tissue quality, tissue thickness and body dimensions.  Good luck.

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.
