What is a Minimizer Bra?  

A minimizer bra redistributes you breast tissue in a way that reduces how far your bust projects forward. This allows you to more easily wear front-button shirts and blouses without gaping. The minimizer cup distributes the breast flesh more toward the underarm, center front, and upper chest. A minimizer bra shifts your breast mass to areas other than forward; basically giving you a rounder and wider breast shape. No bra style can actually reduce breast size.
