Do I need a lift when reducing implant size from 440 cc to 325 cc? (Photo)

I had 400cc implants put in several years ago. Once they settled, I realized they’re way too big. I’ve had a consult to get the implant size reduced & I'm looking at 325cc. The doctor said he didn’t think I would need a lift. I like a more natural look & would love to not have a lift but also am concerned that maybe I do actually need one. I’m 5,7” 170. Thoughts?
