Hi Hun , I’ve just had mine done again due to capsular contracture in my right breast and thought being as I’ve had to have them re done may as well go bigger I’ve gone from 300cc to 500cc and even tho they look fuller and I can see they are bigger it’s not a massive difference if ur only going to go for 100cc bigger I don’t think u will see a big difference tbh I’d at least go 200cc bigger if u can esp if u want them under too X
