Lower portion fits a G/GG, but I don't fill out the top portion. Upper Pole Fullness Options? (Photos)

Breast augmentation with implants will give you more upper pole fullness and balance. This is a common goal, keeping in mind bra and cup size can vary depending upon the brand.

Size would be depositing consultation with your/a plastic surgeon. Again, for upper fullness and not necessarily large size increase.

Choosing the right size and profile breast implants for you. After I measure and discuss goals with my patients, we then look at pictures of women (my patients) with similar measurements with different size and style breast implants. They also get to see what they would look like when the breasts have fully dropped and fluffed and in clothes. You get to see actual results and the surgeon's experience and not a virtual idea of what can be achieved. Women tell me that this process is very helpful in determining what size and style breast implant is right for them. Mildly Sagging Breasts: If your breasts are mildly droopy, a saline or silicone gel implant placed behind the pectoral muscle might help create the illusion of perkiness. That’s because as the implant fills out the top of the breast, it also fills out the bottom, making it look as if the nipple has moved higher. It hasn’t. You can always get a lift later if you feel you are not perky enough when fully settled and healed. Dr. Ted Eisenberg, Board Certified Plastic Surgeon and Author.

From the photos and description of your goals you may want to consider a lift with auto augmentation. This approach uses your own tissue to provide more upper pole fullness. This is different than a fat transfer and does not require an implant. I've included a video that I hope you find helpful.
