a nipple lift will only lift your nipple not the breast so if your breasts have sagged a nipple lift will not be enough to pull it all in to the correct shape.
I am having a oval lift because my areola needs to be reduced and my nipple is too low however my breast is not low and are quite full of tissue.
I have tubular boobs the same as catherine so our case is different to others I think full uplifts are more commonly advised.
I was also told I need a nipple lift without a doubt not a full uplift.
Have a look at the link below it shows the different lifts and the amount of skin removed.. xx
