Breasts do not always look smaller with a lift, but certainly can, especially at some viewing angles. When you look directly at yourself in the mirror, you will have a visual image of your breast that includes the width and height of your breast. This will give you an impression of the overall size of your breast based on dimensions. If you have a breast lift, the breast is almost always lifted and the overall height of the breast is decreased. This will make it look smaller from an AP (straight on) view. The same breasts when compared from a side view will not look much different in size. And they may not fill a bra cup differently either. With that being said, most breast lifts are very good at reshaping the breast, but not great at adding volume to the upper pole of the breast. If you desire significant volume in the upper portion of the breast, you might need a breast implant. Also, I have found that my ability, at least, in reshaping a breast is greatly enhanced when I am able to intentionally remove a small portion of the breast tissue instead of just skin. This will make the breast a bit smaller if this type of technique is used, but the overall shape and longevity of the lift is increased.
