‘Fluffing’ is not a medical term but it is used to refer to settling and dropping of the implant and results in filling out of the lower half of the breast. It can happen with implants both over and under the muscle, although it’s more noticeable in ‘unders’ from what i understand and what i’ve heard on here. However, i had implants under the muscle and mine have ‘fluffed’ and increased by 1 cup size. Hope this helps!
