Will a donut lift and implants work? (Photo)

A full exam is necessary to determine how big each individual can go. This is based on your height, weight, base width, skin elasticity, breast volume and most importantly, your goals.
You would certainly require lowering of your fold, vertical scoring like a tuberous breast and I would encourage an internal mesh bra for additional support.
You could likely get a nice size without using expanders. A periareolar lift would likely be beneficial as well. You have no vertical excess so there is no need for a "lollipop" lift.

Dear JessicaO224,
my preferred lift is a lollipop lift when a periareolar won't do (ie greater than 2cm lift required). The lollipop technique was created by a Canadian plastic surgeon named Elizabeth Hall-Findley and treats the breast as a three dimensional structure instead of two dimensions (anchor - lift). Most importantly it does not require the horizontal component scars that the anchor-lift requires and breasts appear much more natural, lifted, and less boxy. Lastly, the lift lasts longer because the lollipop doesn't rely on the skin to hold the breast up, its actually breast tissue thats being brought together to support the breast and hence improves longevity.

You will need the vertical lift, not doughnut and the size will be limited by your bases. You should be able to go to C cup and maybe a small D.
