Will my breasts get larger as they "drop and fluff" or will they shrink in size? (photo)

Implants initially sit high up because the chest muscles and
surrounding breast tissues have not become accustomed to the implant resulting
in tightness. You have to allow gravity to take effect, and overtime, natural
tissue expansion will allow the implants to fall into place causing your
breasts to appear more natural, softer, and rounder. Once that happens, the
implant will sit directly behind the breast tissue in a natural 45:55 breast
ratio, and the nipples will move up higher.
While the muscle is gradually descending, it is possible for
the breast size to appear different because the implant will not be directly
behind the breast tissue. However, once the implant fully drops down, the
implant will be reinforcing the breast tissue from the back resulting in a
better quality augmentation.
Please note that it is not uncommon for breasts to heal and
adapt to implants at different rates. In fact, the process I described above
can occur quicker in one breast over another.
Unfortunately, patients don’t get to see what the plastic
surgeon sees in the operating room, and as the patients gets in the recovery
room, the breasts begin to swell and muscles begin to tighten. Over the next
3-6 months of recovery, the breast tissue and skin stretch and relax, the body
absorbs all the fluids, and you experience the ‘drop and fluff’. If the breasts
still appear different at that point in time, then you may share your concerns
with your surgeon and they should be able to fix the problem.
You may have to wait 3-6 months for the final results
Patience is key!
Please continue to have regular follow-ups with your surgeon
to make sure your breasts are healing beautifully. Their recovery instructions
should take precedence over all else you read here as they are better informed
about your surgical details.
Hope this helps.

Congratulations on your recent surgery. It's obviously still very early after surgery. Your implants are high and will settle in the coming months. As they "drop and fluff" they will appear larger. Give yourself a full six months to judge your results.

Thank you for your question and photograph.  My strong advice is to wait a full 4-6 months before considering your final result of your breast augmentation.  Your implants are likely still a bit high on your chest and somewhat swollen.  Best of luck.
