My goal is a gentle lift with a natural contour and mild upper fullness - Breast implants or breast lift?

After pregnancy and breastfeeding, my breasts have changed noticeably. I am considering either a breast lift or implants, but I am not looking for a significant increase in size. I prefer a subtle degree of upper-pole fullness and would like to avoid the exaggerated appearance often associated with high-profile round implants. My goal is a gentle lift with a natural contour and mild upper fullness. I am trying to determine whether this result can be achieved with a small implant alone or if a breast lift would be required.
