Can you drop a cup size after liposuction of the upper back?

The bra cup size is the size of your actual breast. The number in the bra size, such as a 34 B, C, or D, indicates the circumference of your chest. So, liposuction your back will not change the size of your breast cup size, but will change the bra number.Thank you for your question, and good luck.

Hello.
Great question. Liposuction of the back does not directly affect the size of your breast; therefore, will not affect cup size. Please visit a board certified plastic surgeon for a detailed surgical plan to achieve your desired results. 

Getting liposuction of the back under tum. local really makes a noticeable improvement and is so easy to undergo.  It won't change the cup size but definitely changes the circumference.
