Eight weeks out my dd was still in binding bra. SHe did not have the keyhole type surgery, they did from arm pit to arm pit. By 8 weeks you would know if the nip's are attaching right, any inflamation would have been delt with, but the area will be red, rawish, tender for any swimming, rough rides. Like that evil dinasour in Animal Kingdom that throws you about.
You will LOVE having normal tops to wear for sure!
