I would like to downsize my breast implants by 2 cup sizes for a more natural look (photos)

I do agree going smaller since your tissue is not supporting the weight of your implants and is bottoming out now. You might consider 200-250 cc's which should bring you down a cup. If you go much smaller, excess skin may become an issue. Your pockets can be tightened laterally when your inferior pockets are tightened so that there is less room for your smaller implants to move around and appear more natural. You might want to also consider going down in profile to moderate plus.

Dear sabrina_s,
breast implant type and sizing selection is a complicated process and requires a detailed consultation that includes a discussion of your goals, a detailed examination, and a lengthy discussion. But the decision will always start and end with the patient. When it comes to sizing, we have all of our patients find 3 photos of their desired breast size. We ask for naked breast photos because clothing can obscure the true size (push up bras). Next, we consult with patients and go over the photos and take detailed breast measurements during a physical exam. Next, we using a sizing algorithm to determine a range of implants that will work based on the exam and the measurements.Lastly, during the operation, we use silicone sizers in the operating room to see how the size actually looks in the breast. We sit the patient up in the operating room, while asleep of course, and compare the sizer result with their desired look photos. If it is too small, we start the process over with a slightly larger implant. We don't stop until we get the perfect match.Of all of my breast augmentation patients, every one of them has been happy with their size due to this detailed and meticulous process. You don't want to invest time and money into a result that is either too big or too small.You should discuss your concerns with a board-certified plastic surgeon and make sure that your surgeon understands your goals.

Your implants are certainly too large and sitting too low
I would go down to a 200 or 250 cc smooth implant with absorbable mesh support
