Do I need a uplift or just a straightforward BA? I'm worried about scars. (photos)

You are likely getting conflicting opinions because you are borderline for a lift. Have you discussed with your surgeons how you'd like to look after surgery? A breast augmentation will add volume to the breasts but will not raise the position of the nipple. If you are wanting the nipple position to be higher, you will want to consider some degree of a lift.

Breast implants alone may be enough to give you the look you desire depending on the volume and type of implant you go for.
If you do need a lift, you can opt for a minimal scar approach such as a crescentic or doughnut uplift where the scar is at the areolar border and fades away nicely.
