Hello Vytask,You have two good choices that are available to you. The most common option is to undergo breast augmentation surgery with insertion of silicone or saline implants. You choose the size of the implants to be inserted. The implants can last for your entire life although you can also change the size in the future or you can even remove the implants if you choose to. The other option is to build breasts by moving fatty tissue from other areas of your body into the breasts. This option requires that you have enough fat to be taken out and moved into the breasts. It often takes 2 or 3 grafting procedures to build B cup size breasts. The fat that is transferred is there permanently and it will be affected by weight gain or weight loss. I hope this helps you.
