They will drop yes but I don’t think they’ll fluff so much, as fluffing is for those with unders, its when the muscle thats been compressing the implants relaxes to allow the implants to fluff, but if you have overs there r is no muscle holding your implants back, you will only drop because of gravity but the fluff is more to do with unders. But let me tell you this with dropping only you will still see a change because the fullness of your boobs will change, your implants will drop to fill the lower pole more and you will loose a bit of upper pole volume if you know what i mean, so filling the lower pole will give you the illusion that your boobs look bigger when in reality they are the same size. However with unders they do actually grow in size with dropping and fluffing because when the muscle that’s been holding them back stops compressing them and relaxes the real size of the implants start to show they will actually become bigger compared to after surgery.
