When will I know my final bra size after my breast augmentation?

My recommendation is to buy a few sports or supportive bras at four to six weeks. There may still be some slight shifting and changing for about six months. At that point you might safely go on a lingerie shopping spree with a professional bra fitter.

Hello!  Thank you for your question!  It typically takes 2-3 months for your final result to be seen in primary breast augmentation. At 3 months, all of the swelling should have resolved and your implants settled into their intended position that was created. In meantime, continue with the instructions, exercises, and garments discussed with your surgeon. Hope that this helps!  Best wishes!  

Dear _chlowil,I understand your concern and it is quite normal to be concerned about the outcome following a breast augmentation surgery. However, you are still in the very early stages of the healing process.Your will need to be patient at this moment and follow what your surgeon has instructed you to do post operatively.At the early stage of the healing process, the tissues around the implants are still swollen. Once the swelling subsides and the implants drop to their final position, you will be able to see the final result of your breast augmentation surgery.Daniel Barrett, MD
