my surgeon said it can take up to a year before unders are fully fluffed but they will softern slowly over time , mine started to feel more like boobs about 10-11 weeks had my op in jan and need to be re messured now coz my bras feel small now lol, my left one took about a week longer to start softning to the right one and even now i get strange zings thought out the boobs but aparently the nerves take around 6 months to fully settle
