Hi there, id say around 4 mnths they stop!! mine now have dropped a little and alot more softer, but they dont shrink in size!! i thought mine had, but after buyng a dd bra, it was too tight! so still wearing a 32e bra.
they just start to look more natural and start to move a little. so don’t worry about them completely shrinking, cos i got worried and i am quite happier with them now, as they are coming 2getha more now, and look better in clothes. they are also still quite high up, so id say around 3-4months they,ll stop XX
