I think when I was still breastfeeding, my breast was really bigger due to milk deposit inside. But after I quit, there will be no milk and no fat deposit inside!
So you'd better prepare to wait for some time until fat deposit again in our breast. My breast is now just a little bit bigger than before, not as big as I was breadfeeding. I don't feel any 揼 or not.
I heard that during breastfeeding your breast will get really big and firm...but after you stop breastfeeding...your breasts will dry up, and become reallly saggy...that's why I was never brave enough to breastfeed... :-(
