It definitely won’t be the strapping. It’s too early days to judge the size of yours babe.. Trust me once the strapping is off and your boobs have some time to settle.. They will drop and fluff and they will grow. You need to let the implant settle to its new environment first cos at the moment, they still look stuck on and squashed to your chest. Mine was like that the first two days, but it’s starting to settle now. Best to do is take everyday pics to see changes. But definitely nothing to worry about hun.x
